Influence of interchain interactions on the electronic properties of neutral and charged oligodiacetylenes carrying bulk substituents
Article Abstract:
The effect of the interchain interactions on the electronic properties of a 'dimer', named [CHD(sub 4)](sub 2), built from two molecules of a fully carbazolyl-substituted oligodiacetylene containing four repeating units is discussed. The simulated photoinduced absorption spectra indicate a substituent-induced strong interaction between the oligomers, due to the very large amount of excess charge on the distorted oligomer, which is spread over its carbazolyl moieties.

Interchain electronic excitations in poly(phenylenevinylene) (PPV) aggregates
Article Abstract:
The semiempirical collective electronic oscillators (CEO) approach based on a time-dependent Hartree-Fock approximation is applied to analyze formation of interchain electronic excitations in PPV aggregates composed of two weakly coupled chain segments. New low-frequency interchain electronic excitations appear upon bringing oligomer chains into close proximity (3-4 A).

Higher triplet excited states of oligo(p-phenylenevinylene)s
Article Abstract:
Properties of the higher excited triplet states of oligo(p-phenylenevinylene)s (OPVn) are investigated with use of the ns-ps and ns-ns two-color two-laser flash photolysis techniques. The lowest triplet excited states of OPVn are generated through the triplet energy transfer process by the first 355-nm laser indication to the triplet sensitizer.
