Abstract

An efficient coupling route to novel π-conjugated comonomers consisting of pyrimidine, thiophene, and bithiophene units was developed. The novel π-donor-acceptor-donor and π- donor-acceptor-acceptor-donor conjugated compounds were prepared by Suzuki heterocoupling and Ni (0)-mediated Ullman homocoupling reactions. Photophysical investigation of these alternating π-donor and acceptor compounds indicated that the ...
