Heteropolyacids (PMo 6 W 6 ) and ferrocene (Fc) were assembled on the glassy carbon electrode for the first time by electrodepositon method, and further combined with reduced graphene oxide (RGO) through the layer-by-layer self-assembly technology, developing a novel non-enzymatic nanocomposite for xanthine (XA) detection. The detection signal of XA was greatly amplified on the Fc-PMo 6 W 6 /RGO nanocomposite modified electrode due to coexist of these three active components. As ferrocene and PMo 6 W 6 all have relatively good electrochemical reversibility, fast electron transfer ability and generation of stable redox forms, meanwhile RGO can enlarge the active surface area of the electrode, increase the conductivity and load of ferrocene and PMo 6 W 6 . Under the optimized conditions, the developed nanocomposite modified electrode displayed superb sensing property towards xanthine with a widely linear range from 5.00 × 10 −8 ∼ 2.03 × 10 -3 M, along with a relatively low detection limit of 1.01 × 10 -8 M. The modified electrode has good stability as it is prepared by the smart combination electrodeposition and layer-by-layer self-assembly. Additionally, the nanocomposite was applied in detecting xanthine in actual samples with acceptable results, demonstrating the feasibility of Fc-PMo 6 W 6 /RGO nanocomposite in routine testing xanthine to some extent.

Conjugated microporous polymers (CMPs) have conjugated skeleton and permanent porosity, and exhibit huge potential in developing novel functional materials for resolving the challenging energy and environment issues. Metal-containing CMPs often exhibited unique properties. In the present manuscript, ferrocene-based conjugated microporous polymers (FcCMPs) were designed and synthesized with 1,1′-dibromoferrocene and 5,10,15,20-Tetrakis(4- bromophenyl) porphyrin (FcCMP-1) or Tetra (p-bromophenyl) methane (FcCMP-2) as building units via Yamamoto coupling. FcCMPs were amorphous, and exhibited excellent thermal and physicochemical stability. The BET surface area of FcCMP-1 and FcCMP-2 was 638 m2/g and 422 m2/g, respectively. In comparison with FcCMP-2, FcCMP-1 displayed better gas storage capacity due to higher porosity. FcCMPs were also used as an adsorbent for removal of methyl violet from aqueous solution, and exhibited excellent adsorption properties due to the interaction between electron-rich conjugated structure of the polymers and methyl violet with cationic groups. Moreover, FcCMPs could be extracted and regenerated by an eluent and then re-used for high efficient removal of methyl violet.Keywords:conjugated microporous polymers (CMPs);ferrocene;gas adsorption;dye removal

Pt/Co and Au are organized into well-defined nanostructures by a simple and mild method, such as dumbbell-like nanorods and core–shell nanorods. The resultant dumbbell-like nanorods show a superior performance in the electrooxidation of formic acid, as compared with core–shell nanorods, Pt-tipped gold nanorods, and commercial Pt/C. This result can be attributed to electronic effect between Au and Pt, heteroatom effect of Co, irregular surface at the tips, and the interface effect.

The elimination of halon and frequent fire accidents have caused an urgent need for the development of high-efficient fire extinguishing agents. ABC dry powder has been paid much attention, and has become one of the most extensively used fire extinguishing agents nowadays owing to its wide applications in various fire protection fields. Therefore, to enhance the fire-extinguishing properties of ABC dry powder, ferrocene was used as the additive to develop a new composite ultrafine dry powder based on an ultrafine ABC dry powder product. Through flame inhibition tests, two performance indexes of the inhibition process, namely temperature drops and flame height variations, were adopted to measure the degree of flame suppression. The experimental results revealed that the temperature drops and flame height variations both increased and then decreased. Moreover, the composite ultrafine dry powder containing 0.7% ferrocene displayed the best inhibitory effect with the maximum temperature drop (152.9°C) and variation rate of flame height (14.01%). Thermogravimetric analysis and differential scanning calorimetry were used to analyze the thermal decomposition of the sample powders. Furthermore, based on the analysis results of the thermal decomposition temperature, weight loss, and other thermodynamic parameters of the sample powders, the reasons for performance advantages of composite ultrafine dry powder containing 0.7% ferrocene were clarified as the faster pyrolysis rate, more absorption of heat, stronger suffocation and chemical inhibition effect. Finally, possible speculations on the suppression mechanisms of composite ultrafine dry powder containing 0.7% ferrocene were proposed.

As a sustainable and environmental-friendly solvent with broad solubility, ionic liquids (ILs) have been utilized as a common medium to dissolve small molecules for industrial and biological applications The performance of these applications is inevitably affected by the transport behaviors of small molecules in ILs Here we present a promising method to acquire significantly accelerated transport of small molecules in ILs by confining ILs in two-dimensional nanochannels. The diffusion behavior of the chosen indicator, ferrocene, was enhanced by up to 40-fold in graphene oxide composed nanochannels compared with bulk systems. Modeling suggests the elevated molecular transport in ILs ascribes to the highly-ordered distribution and depressed interplay of nanoconfined ILs. This phenomenon offers a promising platform to manufacture novel devices of ultrafast molecular transport.

We present two bimetallic architectures cooperatively assembled from trinuclear zirconocene units (Cp3Zr3, Cp = η5-C5H5) and redox-active ferrocene-based ligands (ferrocene carboxylic acid (HFcA) or 1,1-ferrocene dicarboxylic acid (H2FcDA)). Interestingly, single-crystal analysis revealed that Cp3Zr3 units exhibited diverse coordination behaviors upon combination with ferrocene derivatives, ultimately leading to two heterometallic clusters: {Zr3Fc3} with a metallocavitand structure and {Zr12Fc4} with a molecular ring architecture. Notably, the incorporation of ferrocene units provides a photosensitizing center, enabling excellent photocatalytic Fenton-like degradation of methylene blue with efficiencies of 88.86% {Zr3Fc3} and 99.85% {Zr12Fc4}. Furthermore, the DFT calculation results suggest that the HOMO → LUMO transition mainly involves metal-to-core charge transfer (MCCT) from the iron center of the ferrocenyl groups to the Zr-oxo cluster core. This work not only advances the structural diversity of ferrocene-functionalized zirconium-oxo clusters but also offers valuable insights into high-performance Fenton-like photocatalysts.

Ferrocene is a stable metallocene complex with aromatic high-electron π-conjugated system and sandwich structures. We first prepared and characterized a novel ferrocenediamide bridged bis (β-cyclodextrin) chiral stationary phase (FeCDP) to explore its chiral separation function. Its HPLC performance was systematically evaluated by basic, acidic, amphoteric and neutral chiral probes, including triazoles, profens, flavanones, amino acids and β-blocker drugs in reversed-phase and polar organic modes, respectively. The results showed that FeCDP successfully resolved 44 kinds of tested analytes ( R s = 0.66–4.38), of which 36 were completely separated ( R s ≥ 1.5). The best resolutions of different types, such as hexaconazole, ketoprofen, 3'-hydroxyflavanone, phenylalanine and arotinolol on FeCDP were reached at 3.06, 1.90, 4.38, 1.89 and 2.12 in a short time, respectively. Especially, FeCDP could completely resolve imazalil ( R s = 1.97), ketoprofen ( R s = 1.90), dansylated arginine (Dns-Arg, R s = 1.50), pindolol ( R s = 1.42), bevantolol ( R s = 1.41), which were very difficult to be resolved on the conventional CDCSPs. However, under optimal condition, the ordinary CDCSP could only separate 19 analytes with low resolutions ( R s = 0.29–1.27). Compared with the reported similar stationary phases, the HPLC performance of FeCDP was also further improved. Based on the above comparison results, the satisfactory enantioselectivity of FeCDP may be mainly due to the fact that the “ pseudo -cavity” composed of two CDs and a ferrocene diamide, could provide cooperative inclusion for analytes. Meanwhile, the large π-conjugated ferrocenediamide bridging group could also provide hydrogen bonding, π–π stacking, dipole–dipole and hydrophobic interactions, which may promote the chiral recognition effect of FeCDP. Bridge CD-CSP was a versatile chiral separation material in drugs analysis. Graphical Abstract

Inspired by the electron-rich characteristics of ferrocene (Fc), we have strategically integrated this compound into polyaniline (PANI), aiming to modulate the magnetoresistance (MR) and dielectric properties of PANI. The copolymers (P(ANI-co-FcA)) are synthesized by copolymerization of aniline and 1,1′-bis[[(4-aminophenyl)amino]carbon]ferrocene (FcA). The resistivity and temperature-dependent resistivity are measured to unveil the charge carrier transport mechanism, aligning with the Efros–Shklovskii variable-range hopping (ES-VRH) model. Additionally, the MR and dielectric properties are tuned by alternating the FcA content in the main chain of copolymers. MR analysis reveals a positive effect, which is intensified with an increased FcA content. Notably, the MR effect of P(ANI-co-FcA)-3 containing 31.92 wt% FcA attains 1.51% under a magnetic field of 3 T. The real permittivity of copolymers is changed from negative to positive values upon the incorporation of FcA. This research proffers an approach to manipulate the electrical performance of conducting polymer materials for potential applications in electronic devices.

Graphical Penny mix : Three bis-tridentate ferrocene-containing cyclometalated ruthenium complexes have been prepared and characterized, in which the ferrocene units are either substituted on the NNN ligand, on the NCN ligand, or on both sides. A combined experimental and computational study has shown that the electronic coupling between the iron and ruthenium sites is strongly dependent on the connection mode between the two redox-active centers. en This link goes to a English section zh This link goes to a English section Three bis-tridentate ferrocene-containing cyclometalated ruthenium complexes, [(Fcdpb)Ru(tpy)] + ( 1 + ), [(Fctpy)Ru(dpb)] + ( 2 + ), and [(Fcdpb)Ru(Fctpy)] + ( 3 + ), have been prepared and characterized, where Fcdpb is the 2-deprotonated form of 1,3-di(2-pyridyl)-5-ferrocenylbenzene, tpy is 2,2′:6′,2“-terpyridine, dpb is the 2-deprotonated form of 1,3-di(2-pyridyl)benzene, and Fctpy is 4′-ferrocenyl-2,2′:6′,2”-terpyridine. Single crystals of compounds 2 + and 3 + have been studied by X-ray analysis. Complexes 1 + and 2 + displayed two anodic redox waves, whilst three well-separated redox couples were observed for compound 3 + . A combined experimental and computational study suggested that the ferrocene unit on the Fcdpb moiety in compounds 1 + and 3 + was oxidized first. In contrast, the order of the oxidation of ruthenium and ferrocene in complex 2 + was reversed. Metal-to-metal-charge-transfer transitions (MM′CT) have been observed for the singly oxidized states 1 2+ , 2 2+ , and 3 2+ in the near-infrared region. Hush analysis showed that the metal–metal electronic couplings in compounds 1 2+ and 3 2+ were much stronger than those in compound 2 2+ . en This link goes to a English section zh This link goes to a English section 1

Eight ferrocenyl derivatives were synthesized and characterised by NMR, elemental analyses and X-ray single crystal diffraction analysis. The anticancer activities of the eight compounds were assessed where applicable in the two breast cancer cell lines, MCF-7 and MDA-MB-231. It was found that the cytotoxicity of N -Phenyl- N -(2-Methyl-4-Methoxyphenyl)ferrocenecarboxamide ( 4 ) and N , N -bis(4-Methoxyphenyl)ferrocenecarboxamide ( 8 ) correlates to their relatively positive reduction potentials, which may suggest that the cytotoxicity stems from their involvement in electron transfer process. Furthermore, comparing the activity of N , N -bis(phenyl)ferrocenecarboxamide ( 3 ) to that of compounds 4 and 8 suggest that their methoxyl group may undergo demethylation under physiological conditions to generate biologically active species and thus they exhibited better activity in the two breast cancer cell lines compared to compound 3 .

In this work, fluorine containing poly (styrene-acrylate) / ferrocene (FPSA / Fc) composites were prepared by directly mixing FPSA latexes with ferrocene and ethanol co-solvent. Vesicles were obtained while occurring oxidation of composite films, and ruptured to form micropores when carrying out heated process of oxidized films, resulting in increasing roughness and hydrophobicity of composite films. TEM images confirmed that two kinds of structures including ferrocene aggregates and adsorbate latexes existed in composite latexes. The average particle size was decreased after addition of ferrocene. SEM and AFM photos indicated that vesicles and micropores were observed on the oxidized and heated composite films, respectively, and the improvement of surface roughness was subsequently occurred. Water contact angle (WCA) results described that the oxidation had increased the hydrophilicity of composite films, in contrast, the rupture of vesicles had increased the hydrophobicity. The maximum WCA of composite film is up to 121° when the dosage of dodecafluoroheptyl methacrylate (DFMA) and ferrocene were 10.0 and 0.5 wt%, respectively. TGA curves demonstrated that the thermal stability was improved because of the addition of ferrocene and oxidation.

Ferrocene, known for its 'sandwich' structure and Fenton catalytic activity for tumor treatment, its two-dimensional (2D) self-assembly has not yet been exploited for therapeutic applications. Perfluorocarbons (PFCs) can carry and transport oxygen to alleviate tumor hypoxia. Nevertheless, designing ferrocene derivatives with PFC chains to alleviate tumor hypoxia and improve cancer treatment remains a challenge. Here, we first synthesized ferrocene derivatives with different PFC chains (nF-Fc, n = 5, 9, 13) by conjugating perfluorocarbonic acids with 2-(ferrocenylethynyl)aniline (Fc). These derivatives were able to self-assemble into 2D nanosheets, with hydrated particle size decreasing as the chain length increased. The chain lengths also influenced the oxygen-carrying capacity, iron release capacity, and glutathione consumption capacity, all of which impacted their ability to alleviate tumor hypoxia, produce intracellular reactive oxygen species, and enhance chemodynamic therapeutic efficacy. Notably, PFC incorporation altered the mechanism of induced cell death. By elucidating the effects of ferrocene derivatives with different PFC chains on the hypoxic tumor microenvironment (TME) and their therapeutic efficacy, this research advances the development of ferrocene-based 2D materials for cancer treatment and offers a novel approach to optimize compound structures better regulation of the hypoxic TME, ultimately improving therapeutic outcomes.
