Electrochromic polymers electrochemically polymerized from 2, 5-dithienylpyrrole (DTP) with different triarylamine units: Synthesis, characterization and optoelectrochemical properties
چکیده انگلیسی
A series of polymers, consisting both 2, 5-dithienylpyrrole (DTP) and different triarylamine units were synthesized by electrochemical oxidative polymerization. The structures of the monomers, including N-(4-(2,5-di(thiophen-2- yl) −1H-pyrrol-1-yl)phenyl)-N-Phenyl Naphthalene-2-amine (DTP-PNA), 4-(2,5-di(thiophen-2-yl)-1H-pyrrol-1-yl)-N,N-diphenylaniline (DTP-DPA), 4-(tert-butyl)-N-(4-(tert-butyl)phenyl)-N-(4-(2,5-di(thiophen-2-yl)-1H −pyrrol-1-yl)phenyl) aniline (DTP-TBPA), 4-(2,5-di(thiophen-2-yl)-1H-pyrrol-1-yl)-N-(4-(2,5-di(thiophen-2-yl)-1H-pyrrol-1-yl)phenyl)-N-(p-tolyl)aniline (DTP-PTA-DTP), and N-(4-(9H-carbazol-9-yl)phenyl)-4-(2,5-di(thiophen-2-yl)-1H-pyrrol-1-yl)-N-(4-(2,5-di(thiophen-2-yl)-1H-pyrrol-1-yl)phenyl)aniline (DTP-CPA-DTP) were elucidated by FT-IR, 1H NMR, 13C NMR, Mass spectra (MS) and the performance and morphology of resulting polymers (P(DTP-PNA), P(DTP-DPA), P(DTP-TBPA), P(DTP-PTA-DTP), and P(DTP-CPA-DTP)) were determined by cyclic voltammetry (CV), ultra-visible-near infrared (UV-Vis-NIR) spectrophotometer, and scanning electron microscopy (SEM), respectively. The polymers exhibit good reversible multicolor in the visible and NIR region (original yellowish to dusty blue until violet occurred), with better coloration efficiency (CE), fast response time.
