Benzyl substituted benzotriazole containing conjugated polymers: Effect of position of the substituent on electrochromic properties

Benzotriazole containing conjugated polymers for multipurpose organic electronic applications

“…2 illustrate the effects of substitution on optical and electrochemical properties for BTz bearing CPs. Benzyl substituted 27, 55 analogous to the alkyl substituted 19, showed lower optical contrast. It should be noted here that long alkyl chains on the polymer backbone increase the optical contrast for the polymer which can be attributed to the separation between polymer chains.…”

Molecular design of DBT/DBF hybrid thiophenes π-conjugated systems and comparative study of their electropolymerization and optoelectronic properties: from comonomers to electrochromic polymers

“…[1][2][3] In particular, π-conjugated polymers as electrochromic materials have been extensively investigated since they exhibited excellent optoelectronic properties including a variety of colours, a fast colour-switching ability and a high optical contrast as well as their fine-tuning of the band gap (E g ) with minor structural modifications. 4,5 The design and synthesis of novel π-conjugated polymers with specific electrochromic properties have always been one of the primary goals, and have served as a challenging pursuit for most chemists working in the area of electrochromic materials.…”

Effect of substituent position on electrodeposition, morphology, and capacitance performance of polyindole bearing a carboxylic group

“…It is well-known that the position of the substituent had remarkable impacts on the physicochemical and electrochemical properties of polymers [42][43][44]. For example, Yamamoto et al had investigated the photochromism of diarylethenes bearing carboxyl groups at the ortho-,meta-, and para-positions of both terminal phenyl groups [45].…”
