title: Theoretical study of electronic structures and conduction properties of copolymers based on poly(cyclopentadienylene).
abstract: Various quasi-one-dimensional superlattices (copolymers) (AmBn)x of two novel donor-acceptor polymers PPDCF ([A]x) and PPDCN ([B]x) based on poly(cyclopentadienylene) (PPD) and belonging to the class of type II staggered superlattices were investigated using a negative factor counting method in the tight-binding approximation. Both PPDCF and PPDCN consist of a bicyclopentadienylene unit bridged by an electron-accepting group >C=CF2 in PPDCF and >C=C(CN)2 in PPDCN. The trends in the electronic structures and conduction properties of the copolymers (AmBn)x as a function of the block sizes m and n, arrangement of the units (periodic or random) in the copolymer chain, and length of the copolymer chain are discussed.
