F. Dietz et al., BAND-STRUCTURE OF QUASI-1-DIMENSIONAL POLYCONDENSED PI-SYSTEMS .3. ENERGY-SPECTRA OF ANTIAROMATIC POLYMERS, Macromolecular theory and simulations, 3(1), 1994, pp. 241-253
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.
