Abstract
Alternating polyfulorene copolymers, which have donor-acceptor-donor segments in
between the fluorene segments were synthesized and characterized. The donoracceptor-
donor monomers, namely, 5,8-bis(5-bromothiophen-2-yl)-2,3-bis(3-(tert-butyl
dimethylsilyloxy)phenyl)quinoxaline and 5,8-bis(5-bromothiophen-2-yl)-2,3-bis(3-(2-(2-
methoxyethoxy) ethoxy)phenyl)quinoxaline were prepared starting from 3-bromophenol
and 2,1,3-benzothiadiazole. The polymers were synthesized by using Suzuki coupling
polymerization reaction. The resulting polymers showed good solubility in chloroform.
The electrochemical behaviors of the copolymers were characterized by cyclic
voltammetry. The synthesized compounds were characterized using spectroscopic
techniques
