Abstract: The effect of multi-neighbour interaction along the copolymer chain on its electronic density of states (DOS) has been investigated using matrix block negative factor counting (NFC) method in the case of the various periodic and aperiodic copolymers (AmBn)x of the two silole based donor-acceptor polymers PSICO (A)x and PSICN (B)x. The results obtained are found to be qualitatively similar to those obtained using NFC method in the tight binding approximation implying that as far as the trends in the electronic structures and conduction properties of these copolymers are concerned, they are reasonably well reproduced when interaction up to first neighbour along the copolymer chain only are considered.
