Abstract

We present the results of calculations on the electronic properties and electrical polarizabilities of polyaromatic and polyarylene vinylene systems. The n-doping of polyaromatics is shown to produce a marked polarizability increase due to both geometrical relaxation and charge transfer processes. Differences between p-type and n-type doping are stressed. The advantages of fused-ring and/or quinoid structures are illustrated. Thieno[3,4-c]thiophene oligomers are calculated to display extremely high polarizabilities. In polyarylene vinylenes, the combination of aromatic and vinylene moieties is found to lead to promising nonlinear optical characteristics.
