Modification and Electrochemical Properties of Poly(phenylazomethine) Derivatives

Abstract

Summary: Oligo(phenylazomethine)s (OPAs) and aniline-capped OPAs (OPA's) are used as model compounds of polyphenylazomethine (PPA), and their fundamental properties and their modification methods are investigated. Cyclic voltammograms of bis(diphenylmethyleneamino)benzene (OPA2 0 ) showed irreversible redox response in the presence of trifluoroacetic acid. A selective synthesis of oligophenanthridine was achieved through the photocyclization of OPA2 0 in concentrated sulfuric acid. Stepwise complexation behavior in dendritic poly(phenylazomethine)s (DPAs) was supported by the shell-selective reduction of the imines. Using the shell-selective reduction method and the terminal-modification method of the DPAs, the core and terminals of DPAs were functionalized by ferrocene units, respectively.

Electrochromic Organic–Metallic Hybrid Polymers: Fundamentals and Device Applications

“…So far, we have reported several types of organic-metallic hybrid polymers, which were formed during the metal-ion assembly of polyaniline [41][42][43] and stepwise assembly of metal ions in dendritic [44][45][46][47][48][49][50][51][52][53] or cyclic 54-61 polyphenylazomethines. Organicmetallic hybrid polymers that are formed by the complexation of metal ions with -conjugate organic ligands are promising electrochromic materials.…”
