摘要：
We proposed a tight-binding model for diblock copolymers. Electronic structure calculations presented for poly(p-phenylene)/polyacetylene revealed that the band gap of copolymers can be tuned by changing the concentration ratio of the homopolymers. The effect of homopolymer interactions on the band structure of copolymers has been studied. The results were compared with the known experimental data.
