摘　　要：在紧束缚近似下 ,建立了共聚物 (-PPPx)—(PAy)-的物理模型 ,研究了组成共聚物的均聚物单体对体系晶格结构、能带结构等的影响 。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.
