In the dehydration of fructose to 5-hydroxymethyl furfural (HMF), in situ produced water weakens the acid strength of the catalyst and causes the rehydration of HMF, causing unsatisfactory catalytic activity and selectivity. In this work, a class of benzenesulfonic acid-grafted metal–organic frameworks with strong acidity and hydrophobicity is obtained by the direct sulfonation method using 4-chlorobenzenesulfonic acid as sulfonating agent. The resultant MOFs have a specific surface area of greater than 250 m 2 ·g −1 , acid density above 1.0 mmol·g −1 , and water contact angle up to 129°. The hydrophobic MOF-PhSO 3 H exhibits both higher catalytic activity and selectivity than MOF-SO 3 H in the HMF synthesis due to its better hydrophobicity and olephilicity. Moreover, the catalyst has a high recycled stability. At last, fructose is completely converted, and 98.0% yield of HMF is obtained under 120 °C in a DMSO solvent system. The successful preparation of the hydrophobic acidic MOF provides a novel hydrophobic catalyst for the synthesis of HMF.

52–94% yields of 5-hydroxymethylfurfural (HMF) from carbohydrates such as monosaccharides, disaccharides and polysaccharides were achieved using PEG-OSO3H or PS-PEG-OSO3H as reusable catalysts in a DMSO/H2O reaction system. Using polymer-supported catalysis, corn stover could also be effectively transformed into HMF and furfural.

Bamboo, as a renewable and biodegradable polymer resource, is currently used to develop environmentally-friendly polymer materials. However, obtaining bamboo-derived foam materials through sol–gel method encounters challenges in controlling pore structures and foam performance, primarily stemming from weak hydrogen bonding interactions among cellulose, hemicellulose and lignin. In this work, robust bamboo-derived foam materials are developed by freeze-drying all-component bamboo gels. To obtain gels with stable three-dimensional network structure, tannic acid (TA) is used to accelerate the sol–gel transition of the all-component bamboo suspension, by mediating the hydrogen bonding interactions among various biomass components. As a result, the gelation time is reduced from 60 h for the bamboo suspension down to 6 h for the TA/bamboo suspension. After freeze-drying the TA/bamboo gels, foam materials with a low density of ~ 0.08 g/cm 3 and satisfactory thermal insulation can be obtained. Notably the addition of TA not only preserves all components of the bamboo biomass in the foam materials, but also improves the compressive strength of the bamboo-derived foam material by 240% with respect to that pure bamboo foam. This study offers a sustainable and efficient approach for developing high-performance porous materials from all-biomass resources. Graphic abstract

An easy and effective way to synthesize dual-functionalized cellulose derivatives with processability and fluorescence functionality by one-pot modification of successive esterification and carbonation under mild condition is established with the use of DMSO/DBU/CO 2 system. Accordingly, four kinds of dual-functionalized cellulose derivatives with rather good fluorescent response are obtained. After blending the synthesized dual-functionalized cellulose derivative with cellulose acetate as functional additive in solution, cast film with the elastic modulus , stress and strain reaches to 2.2 GPa, 34.1 MPa and 5.7% is prepared. Besides, the cast film also exhibits the ability to detect the pH value at 12–14 with detection accuracy of 0.4 through the change of fluorescent color. This research shows a simple but effective way to prepare dual-functionalized cellulose derivatives for the high-quality applications in field of detection.

The facile preparation of sustainable polymer gel electrolyte by using renewable natural polymers has attracted much attention, and the development of new polymer gel electrolyte materials largely depends on the facile design and preparation of a polymer network capable of effectively loading external high-performance electrolyte. In this study, taking the advantages of a newly developed solvent system superbase/DMSO/CO 2 for cellulose, a new and facile “all-in-one” strategy to engineer cellulose into flexible cellulosic poly (protic ionic liquids)/PVA-based composite organic ionogel electrolyte (CPOIE) has been developed through in situ derivatization, chemical cross-linking and compositing strategy using succinic anhydrides, epichlorohydrin, and polyvinyl alcohol, respectively. The findings show that CPOIEs exhibit both excellent mechanical properties and superior electrochemical properties (high ionic conductivity up to 4.2 mS/cm at room temperature with a wide electrochemical window of 2.0 V for C 1 P 1 OIE sample). A supercapacitor assembled by using the as-prepared C 1 P 1 OIE sample delivers a good specific capacitance of 122 F/g at 0.5 A/g, a high energy density up to 17.38 Wh/Kg at room temperature and an excellent cyclic stability up to 8000 cycles.

Cellulose graft copolymers having well-defined structures could incorporate the characteristics of both the cellulose skeleton and side chains, providing a new method for the preparation functionalised cellulose derivatives . Herein, a series of multifunctional cellulose grafted, alternating 3,4-dihydrocoumarin (DHC) and epoxide (EPO) copolymers (cell- g -P(DHC- alt -EPO)) were prepared in a metal-free DBU/DMSO/CO 2 solvent system without adding additional catalyst. Four examples of cell- g -P(DHC- alt -EPO) with tunable thermal and optical properties were synthesized by copolymerization of DHC with styrene oxide (SO), propylene oxide (PO), cyclohexene oxide (CHO) or furfuryl glycidyl ether (FGE) onto cellulose. The nonconjugated cell- g -P(DHC- alt -EPO) showed UV absorption properties with the maximum absorption peak at 282 nm and 295 nm and photoluminescence performance. A clustering-triggered emission mechanism was confirmed and consistent with DFT theoretical calculations. In DMSO solution, the copolymer (DHCSO5) with DP of 11.64 showed ACQ behaviour as the concentration increased. In addition, DHCSO5 had good antioxidant capacity with an instantaneous radical scavenging activity of 2,2-diphenyl-1-picrylhydrazine (DPPH) up to 65 % at a concentration of 40 mg/ ml and increased to 100 % after 30 min. Thus, the multifunctional cell- g -P(DHC- alt -EPO) materials had a variety of potential applications in the fields of fluorescent printing, bio-imaging, UV- shielding and antioxidants.

Two different kinds of configurations of 1,4-bis[2-(4-pyridyl)ethenyl]-benzene( trans -bpeb and cis -bpeb) were achieved, and a bpeb dimer was synthesized in dimethyl sulfoxide(DMSO). Compared with the previous work that synthesized the bpeb dimer or polymer in crystal with a template agent needed, the reaction occurred in a solution phase in the present method. A hand-held ultraviolet lamp(365 nm) with the power of 12 W and the Watt density of 0.35 mW/cm 2 can realize the photodimerization of bpeb, instead of the high-power mercury lamp in most previous studies. Unlike other 2+2 cycloaddition in liquid state using catalysts even noble metals, no catalysts were required here, which is cost-saving. Only the trans -pbeb can start the cycloaddition and the formation of the close J-aggregations of trans -pbeb in DMSO is a precondition for explaining the 2+2 photodimerization. The productivity for the 2+2 cycloaddition product was achieved as 55.6%.

The co-solvent-assisted interfacial polymerization (CAIP) strategy has proven to be an effective method for fabricating high-performance forward osmosis (FO) membranes. However, current research primarily focuses on the role of co-solvents in conventional interfacial polymerization (IP) technology, with relatively limited studies on unconventional IP technologies. This study explores support-free interfacial polymerization (SFIP) by incorporating dimethyl sulfoxide (DMSO) as a co-solvent. The impact of DMSO on polyamide (PA) structure and membrane performance is systematically investigated throughout the SFIP process. At a DMSO concentration of 1.5 w/v%, SFIP-D1.5 membrane exhibited a high water flux of 29 LMH without a significant increase in reverse salt flux. This phenomenon can be attributed to the dual role of DMSO in promoting monomer diffusion and inducing swelling of the SFIP-PA film. Furthermore, the SFIP-D1.5 membrane exhibited stable performance over 24 h operation and maintained comparable anti-fouling properties during multi-cycle fouling tests. This study reveals the distinct behavior of DMSO in the SFIP process compared to conventional IP, and demonstrates the potential of the CAIP strategy within unconventional IP techniques. This provides a promising approach to enhance both the selectivity and permeability of TFC FO membranes fabricated using strong solvents as co-solvents.

The large open-circuit voltage deficit ( V oc,def ) is the key issue that limits kesterite (Cu 2 ZnSn(S,Se) 4 , [CZTSSe]) solar cell performance. Substitution of Cu + by larger ionic Ag + ((Ag,Cu) 2 ZnSn(S,Se) 4 , [ACZTSSe]) is one strategy to reduce Cu–Zn disorder and improve kesterite V oc . However, the so far reported ACZTSSe solar cell has not demonstrated lower V oc,def than the world record device, indicating that some intrinsic defect properties cannot be mitigated using current approaches. Here, incorporation of Ag into kesterite through a dimethyl sulfoxide (DMSO) solution that can facilitate direct phase transformation grain growth and produce a uniform and less defective kesterite absorber is reported. The same coordination chemistry of Ag + and Cu + in the DMSO solution results in the same reaction path of ACZTSSe to CZTSSe, resulting in significant suppression of Cu Zn defects, its defect cluster [2Cu Zn + Sn Zn ], and deep level defect Cu Sn . A champion device with an efficiency of 12.5% (active area efficiency 13.5% without antireflection coating) and a record low V oc,def (64.2% Shockley–Queisser limit) is achieved from ACZTSSe with 5% Ag content.

Deprotonated flavonoids typically undergo efficient nonradiative relaxation in solution, rendering them nonemissive. In this study, we successfully activate the fluorescence of such anions by embedding five representative flavonoids─galangin, apigenin, luteolin, kaempferol, and quercetin─into DMSO-doped poly(vinyl alcohol) (PVA/DMSO) films. The unique microenvironment of the composite film provides dual functionalities: intrinsic microbasicity facilitates flavonoid deprotonation, while spatial constraints effectively suppress the nonradiative decay pathways. Consequently, strong visible-light emission is observed for all flavonoids except galangin upon excitation at 440 nm. Time-dependent density functional theory calculations were employed to model the emission energies of various anionic species. By correlating the calculated trends with experimental spectra, we identify the emissive species as anions deprotonated specifically at the C4′–OH position, rationalizing the absence of emission from galangin, which lacks this moiety. This work not only demonstrates a general strategy to unlock the fluorescence of nonemissive anionic chromophores through synergistic matrix control but also establishes PVA/DMSO films as a versatile platform for modulating the photophysics of charged organic molecules.

A large–grain and highly crystalline Cu 3 BiS 3 thin film is successfully prepared by a dimethyl sulfoxide (DMSO)–based solution coating process . Without involving post sulfurization , Cu 3 BiS 3 absorber with grain size of ~ 1 µm has been achieved via a short-time drying of spin–coated precursor film on a hot plate at relatively low temperatures (< 300 °C). Our Cu 3 BiS 3 film exhibits a direct band gap of 1.47 eV with high absorption coefficients (~ 7 × 10 4 cm −1 ). Hall effect measurements reveal a p–type conductivity with hole concentration of ~ 10 16 cm −3 and mobility of 52.83 cm 2 /(V s). Moreover, an initial Cu 3 BiS 3 thin film solar cell with the device structure of glass/Mo/Cu 3 BiS 3 /CdS/ZnO/ITO/Al is fabricated, achieving a definite conversion efficiency of 0.17%. The mild preparation condition promises great potential of current method in realizing Cu 3 BiS 3 solar cells on temperature-sensitive substrates such as flexible polymer through an energy efficient way. The Cu 3 BiS 3 has thus been presented as a promising absorber material for solar cell applications.

A bifunctional comonomer β -methylhydrogen itaconate was synthesized to prepare high molecular weight poly [acrylonitrile- co -( β -methylhydrogen itaconate)] [P (AN- co -MHI)] by mixed solvents polymerization, which was used as carbon fiber precursor instead of acrylonitrile terpolymers. The effect of dimethyl sulfoxide (DMSO)/deionized water ratios on the polymerization, structure and stabilization of P (AN- co -MHI) was studied by elemental analysis, UV-Visible Spectroscopy, fourier transform infrared spectroscopy (FTIR), X-ray diffraction (XRD) and differential scanning calorimetry (DSC). The highest viscosity-average molecular weight (76.72 × 10 4 g/mol) of P(AN- co -MHI) was obtained in the mixed solvents of DMSO/deionized water = 10/90 (wt/wt) due to the zero chain transfer constant of deionized water for radical ~ ~ ~AN·, which is 10 times larger than that of P(AN- co -MHI) copolymers prepared in DMSO solution polymerization under the same conditions and is beneficial to improving the tensile strength of resulting carbon fiber. The composition of P(AN- co -MHI) was controlled by the ratio of DMSO/deionized water in the mixed solvents, it is attributed to the changes of AN/MHI ratio taking part in the polymerization reactions, which is caused by the different solubility of AN in the mixed solvents. From elemental analysis and FTIR studies, it can be found out that the content of MHI in P(AN- co -MHI) copolymer becomes larger with the increase of DMSO content in the mixed solvents. The FTIR, XRD and DSC results show that the stabilization of P(AN- co -MHI) copolymer was significantly improved by MHI compared with PAN homopolymer and poly (acrlonitrile-methyl acrylate-acrylic acid) terpolymer, such as larger extent of stabilization, lower initiation temperature and smaller E
a of cyclization, which is beneficial to preparing high performance carbon fiber.
