Abstract
The band structure of a class of quasi 1-dimensional (1-D) polymers wi th anti-aromatic structural units - anti-aromatic polymers (AAP) - has been investigated theoretically. The energy gap (EG) of the AAP is si gnificantly smaller compared to the EG of polymers with aromatic build ing blocks having the same number of pi-centers in the elementary unit s. The influence of the electron correlation in the calculation of the EG is investigated. As with the antiaromatic molecules the Jahn-Telle r distortion influences the geometric configuration of the AAP.
