Abstract
Molecular orientations in oligothiophene (Tn) - and oligo- (p-phenylen evinylene) (Pn) - nanoaggregates are investigated by time-resolved flu orescence anisotropies and polarized light scattering. Tn- and unsubst ituted Pn-molecules align parallel to each other, but not the substitu ted Pn's. Electronic absorption and fluorescence spectra of the orient ed systems are strongly altered against the monomers and the fluoresce nce quantum yields are strongly reduced.
