In this paper, carboxylated cellulose (CLC) dissolved in [BMIM]Cl as a soft template combined with the functional group (−NH2, −SH)-grafted poly(3,4-ethylene dioxythiophene) (PEDOT) derivatives was synthesized by an in situ polymerization method. Structural analysis revealed that CLC increased the degree of conjugation of the polymers in the composites and also led to the formation of the fibrous and sheet structure of the composite. The results of the electrochemical performance measurements revealed that the electrode modified by PEDOT-MeNH2/CLC and PEDOT-MeSH/CLC had detection limits (S/N = 3) of 0.38(0.1–380 μM) and 0.042(0.02–520 μM) for the detection of guanine (G), while for the detection of uric acid (UA), the corresponding detection limits (S/N = 3) were 0.255(5–400 μM) and 0.085(0.4–650 μM). The PEDOT-MeSH/CLC-based electrochemical sensor also possessed a wide linear response with the detection limits of 0.077(0.6–620 μM) and 0.144(0.2–460 μM) for the simultaneous detection of UA and G, respectively.

The development of weather-independent photovoltaics is a persistent goal for energy technique. Herein we develop a category of hybridized dye-sensitized solar cells (DSSCs) from cost-effective poly(3,4-ethylenedioxythiophene) (PEDOT) derivate counter electrodes and mesoscopic titanium dioxide/long persistence phosphors ( m -TiO 2 /LPPs) composite photoanodes. Using the solar energy storage and emission performances of LPP phosphors, the final m -TiO 2 /LPPs photoanodes are demonstrated to store unabsorbed incident light and to persistently emit monochromatic light for re-exciting photosensitizers. The optimized photovoltaics yield a maximized power conversion efficiency of 10.07% under simulated sunlight irradiation (100 mW cm −2 , air mass 1.5 global) and durable energy output lasting for hours when ceasing solar illumination. The application of m -TiO 2 /LPP photoanodes in the hybridized DSSCs provides new opportunities of making multi-energy integrated photovoltaics for persistent power generation free of sun illumination.

Two new 3,4-ethylenedioxythiophene (EDOT) derivatives, (2 R )-(2,3-dihydrothieno[3,4-b][1,4]dioxin-2-yl)methyl 2-phenylpropanoate (( R )-EDTM-PP) and (2 S )-(2,3-dihydrothieno[3,4-b][1,4]dioxin-2-yl)methyl 2-phenylpropanoate (( S )-EDTM-PP), were synthesized and electropolymerized in dichloromethane (CH 2 Cl 2 ) and terabutylammonium hexafluorophosphate (Bu 4 NPF 6 ) system. As chiral electrodes, poly((2 R )-(2,3-dihydrothieno[3,4-b][1,4]dioxin-2-yl)methyl 2-phenylpropanoate) (( R )-PEDTM-PP) and poly((2 S )-(2,3-dihydrothieno[3,4-b][1,4]dioxin-2-yl)methyl 2-phenylpropanoate) (( S )-PEDTM-PP)-modified glassy carbon electrodes (GCEs) were employed to successfully recognize 3,4-dihydroxyphenylalanine (DOPA) enantiomers. Cyclic voltammetry presents that ( R )-PEDTM-PP and ( S )-PEDTM-PP had good redox activity and stability. Spectroelectrochemistry studies revealed ( R )-PEDTM-PP and ( S )-PEDTM-PP polymers have electronic bandgap of 1.68 and 1.66 eV, and could be reversibly oxidized and reduced accompanying with obvious color changes from dark blue to light purple. In addition, the electrochemical behavior, structural characterization, thermal stability, morphology and circular dichroism of ( R )-PEDTM-PP and ( S )-PEDTM-PP films were investigated in detail. © 2015 Wiley Periodicals, Inc.

Two amino acid-functionalized poly(3,4-ethylenedioxythiophene) (PEDOT) derivatives, poly(N-(tert-butoxycarbonyl)-L-leucyl(3,4-ethylenedioxythiophene-2′-yl)methylamide) (PEDOT–Boc–Leu) and poly(L-leucyl(3,4-ethylenedioxythiophene-2′-yl)methylamide) (PEDOT–Leu) were synthesized electrochemically via potentiostatic polymerization of corresponding monomers N-(tert-butoxycarbonyl)L-leucyl(3,4-ethylenedioxythiophene-2′-yl)methylamide (EDOT–Boc–Leu) and L-leucyl(3,4-ethylenedioxythiophene-2′-yl)methylamide (EDOT–Leu), which were synthesized by grafting Boc-L-leucine and L-leucine into a 3,4-ethylenedioxythiophene (EDOT) side chain. The electrochemical behaviors, structural characterization, circular dichroism, spectroscopic properties, surface morphology, electrochromic properties and thermal stabilities of PEDOT–Boc–Leu and PEDOT–Leu films were systematically investigated. These L-leucine grafted PEDOT derivatives displayed excellent reversible redox activities, rough and compact surface, and good thermal stability. The circular dichroism spectra suggested the chirality of these polymers. Importantly, the introduction of the L-leucine group enhanced the electrochromic properties of PEDOT and resulted in high contrast ratios (ΔT% = 49% at 600 nm for PEDOT–Boc–Leu) and high coloration efficiencies (431 cm2 C−1 at 960 nm for PEDOT–Leu). Satisfactory results implied that the obtained polymer films can probably be further developed in various applications, such as electrochromic devices, optical displays and chiral recognition.
