Preparation of neutrally colorless, transparent polynorbornenes with multiple redox‐active chromophores via ring‐opening metathesis polymerization toward electrochromic applications

Abstract: A new electrochromic norbornene derivative containing triphenylamine groups (NBDTPAC8) was synthesized using norbornene amine and bromotriphenylamine. NBDTPAC8 was used in ring-opening metathesis polymerization to obtain poly (NBDTPAC8) using different Grubbs' catalysts and followed by hydrogen reduction to obtain poly(HNBDTPAC8). The glass transition temperatures (T g ) of poly(NBDTPAC8) and hydrogenated poly(HNBDTPAC8) were 132 and 89 C, respectively. Poly (HNBDTPAC8) film exhibited a fluorescence maximum ar… Show more

“…As depicted in Figure , both PNBE-TFVE and PNBE–PFCB films show good transmittance (>90%) from 550 to 1100 nm. This result based on a PNBE–PFCB film is comparable to the reported transparent PNBs. The transmittance quickly decreases to near 0% in the UV region (<380 nm) due to the absorption of the aromatic rings of polymers. The cross-linking procedure had no effect on the transparency of the polymer.…”

“…Conducting polymers (CPs) have been extensively studied in both fundamental and practical perspectives due to their applications in various fields, such as solid electrolyte capacitors, printed wiring boards, indium tin oxide (ITO) substitution, organic light‐emitting diodes, organic solar cells, electrochromics, biosensors, and organic field‐effect transistors . CPs as eletrochromic materials have attracted many scientists' attention because of their outstanding advantages over transition metal oxides, such as long‐term stability, high contrast ratio and coloration efficiency (CE), fast response time, low switching potential, and the ease of color control through structure modification …”
