Two bis-chalcone derivatives, (2E,6E)-2,6-bis[(thiophen-2-yl)methylene]cyclohexanone (C1) and (2E,6E)-2,6-bis[(furan-2yl)methylene]cyclohexanone (C2)-based electrochromic (EC) nanofibers were produced in the presence of poly(methyl methacrylate) (PMMA) as supporting polymer using the electrospinning technique. The scanning electron microscopy (SEM) and energy dispersive X-ray spectroscopy were used to examine morphology and chemical compositions of nanofibers before and after stability test. SEM images of the obtained smooth and bead-free nanofibers before the stability test showed that both bis-chalcone derivatives were homogeneously dispersed on the surface of the electrospun nanofibers. Nanofibers of bis-chalcone derivatives were characterized with Fourier-transform infrared spectroscopy. The electrochemical and EC properties of these bis-chalcone derivatives were investigated. The C1-PMMA nanofiber-based electrochromic device (ECD) showed higher DT max (41.47%) than that of the C2-PMMA nanofiberbased ECD (4.67%) during coloration/bleaching at 715 nm. The switching times for coloration and bleaching of C1-PMMA nanofiber-based ECD were found to be 4.42 and 1.12 s, respectively, and the coloration efficiency was 136.18 cm 2 /C. Repeated cyclic voltammograms and 1000 cycles of chronoamperometric measurements of the bis-chalcone derivatives indicated that ECDs have long-term redox stability.

“…The optimized E EP , which was found to be slightly lower than the potential assigned to the monomer polymerization (1.345 V vs. Ag/Ag + for FcCPDT in this paper), is in accord with the reports concerning the electrodes prepared via EP technology. 35,37 The low-magnication SEM images in Fig. 3a reveal the trend of polymer growth at E EP from 1.1 to 1.5 V vs. Ag/Ag + .…”

“…To pander to the fast development of various fields, highly urgent demand is to design and synthesize new molecules used as CP precursors according to the principle of adjustable band gap that affects optical and electrical properties . So far, the CPs based on thiophene units such as bithiophenes, 2‐(thiophen‐2‐yl)furan, dibenzothiophenes, thieno[3,2‐ b ]thiophenes, benzodithiophenes, and cyclopentadithiophenes have been fabricated and constructed various organic electronic and photonic devices.…”

A novel co-monomer 5- (2,3-dihydrothieno[3,4-b] [1,4]dioxin-5-yl)-1H-indole (EDTI), based on the combinations of indole and 3,4-ethylenedioxythiophene (EDOT) groups, was synthesized and electrodeposited into flawless free-standing flexible poly (5-(2,3-dihydrothieno[3,4-b][1,4]dioxin-5-yl)-1H-indole) (PEDTI) film by Rui Wang, Guo Ye, Weiqiang Zhou and their colleagues. The colors of as-prepared PEDTI film could switch reversibly from purple to brown during the n-and p-doping. Fluorescence spectral studies revealed PEDTI was good blue-green light emitter with the best emission wavelength 461 nm and 488 nm. These results implied that PEDTI had potential applications for photoelectric devices.46929 Thermal conductivity improvement in electrically insulating silicone rubber composites by the construction of hybrid three-dimensional filler networks with boron nitride and carbon nanotubes 47016 High-quality freestanding flexible poly (5-(2,3-dihydrothieno[3,4-b][1,4]dioxin-5-yl)-1H-indole) film: Electrosyntheses, characterization, and optical properties
