Methodological research on the electronic properties of polymers and development of computer programmes (POLYMOL, PLH, VEH)
for calculating band structure and properties of polymers. Role of long-range electrostatic interactions and analysis
of the interplay between electronic (de)localisation, exchange effects, size of energy bands and the importance
of electronic correlations. Development of original methodologies to determine the asymptotic electronic and vibrational
(hyper)polarizabilities of the infinite polymer chains.
Theoretical interpretation of X-Ray (ESCA) or UV-induced photoelectron spectra of polymers and their use
for the explanation of substitution, conformation and disorder effects.
Theoretical design of highly conducting organic polymers and molecular engineering of polymeric materials of
interest in nonlinear optics.
