New donor–acceptor copolymers with ultra-narrow band gap for photovoltaic application
Two novel donor–acceptor (D–A) copolymers P1 and P2 with the thiazoloquinoxaline repeating acceptor moiety and different donor moieties of benzo[1,2- b :4,5- b ']dithiophene and isomeric benzo[2,1- b :3,4- b ']dithiophene have been prepared. The polymers show light absorption at 300–1200 n...

']dithiophene have been prepared. The polymers show light absorption at 300–1200 nm and a band gap width of 0.98 and 1.14 eV, respectively. The energies of the HOMO (–5.42 and–5.29 eV) and LUMO (–3.90 and–3.83 eV) levels of polymers
P1
and
P2
have been determined. The absorption maximum for polymer P1 in the long-wavelength region is red-shifted by 161 nm, which is caused by stronger charge transfer in P1 as compared with

P1
in comparison with that of
P2
indicates that interchain π–π stacking interactions are more efficient in
