Abstract

Here we report the preparation of two solution processible polymers; poly(2-(5-(2-(2-octyldodecyl)-2H-benzo[d][1,2,3]triazol-4-yl)thiophen-2-yl)-5-(thiophen-2-yl)thiazolo[5,4-d]thiazole) (PBTTz) and poly(2-(5-(9,9-dioctyl-9H-fluoren-2-yl)thiophen-2-yl)-5-(thiophen-2-yl)thiazolo[5,4-d]thiazole) (PFTTz) which are multichromic electroactive polymers. PBTTz was synthesized via Stille coupling polymerization whereas PFTTz was synthesized via Suzuki coupling polymerization. Both polymers were coated on ITO slides and their electrochromic properties were investigated. The results of the PBTTz were also compared with a previously published polymer to investigate the linear and branched alkyl chain effect. The polymers were compared through their optical properties and UV-Vis spectroelectrochemistry. (C) 2014 Elsevier Ltd. All rights reserved.
