An ambipolar peryleneamidine monoimide-fused polythiophene with narrow band gap.
A peryleneamidine monoimide-fused terthiophene with a band gap of 1.4 eV has been synthesized. The donor-acceptor system can be electropolymerized to generate a functionalized polythiophene with a band gap of 0.9 eV and with ambipolar characteristics showing high electroactivity in both the p- and the n-doping process. This is the first example of a p-type conjugated polymer in direct conjugation with n-type perylenemonoimide moieties.
