Synthesis Of Benzotriazole Bearing Donor Acceptor Type Electroactive Monomers Towards High Optical Contrast And Fast Switching Electrochromic Materials

Synthesis of new electroactive monomers are highly desired since these compounds can be
utilized as active layers in many device applications such as ECDs, LEDs and solar cells.
EDOT (3,4 ethylenedioxythiophene) and thiophene bearing polymers were also proven to be
excellent candidates as electrochromic materials. Benzotriazole can be coupled to EDOT and
thiophene to yield materials that can be polymerized to give donor acceptor type polymers.
These materials are promising candidates as components in fast switching polymeric
electrochromic devices. Donor acceptor type materials / 2-dodecyl-4-(2,3-dihydrothieno [3,4-
b][1,4]dioxin-5-yl)-7- (2,3-dihydrothieno[3,4-b] [1,4] dioxin-7-yl)-2H-benzo
[d][1,2,3]triazole and 2-dodecyl-4,7-di(thiophen-2-yl)-2H-benzo[d][1,2,3]triazole were
synthesized via N-alkylation, bromination, stannylation and Stille coupling reactions.
Electrochemical and electrochromic properties of the polymers were examined in detail.
