2-Dodecyl benzotriazole and 9,9-dioctylfluorene containing alternating copolymers poly((9,9-dioctylfluorene)-2,7-diyl-(2-dodecyl-benzo[1,2,3] triazole)) (P1), poly((9,9-dioctylfluorene)- 2,7-diyl-(4,7-bis(thien-2-yl) 2-dodecyl-benzo[1,2,3] triazole)) (P2), poly((9,9-dioctylfluorene)- 2,7-diyl-(4,7-bis(3-hexylthien-5-yl) 2-dodecyl-benzo[1,2,3] triazole)) (P3) were synthesized via Suzuki polycondensation. Electronic and optical properties of resulting polymers showed that all polymers are both p and n dopable and have multicolored electrochromic states. HOMO and LUMO values, band gaps and spectral response of polymers upon externally applied potential and trifluoro acetic acid (TFA) addition were given in detail.
