Abstract
Three new phenylene vinylene oligomers containing either a bis(oligoether)phenyl ring or a benzothiadiazole
central unit and either carbazole or triphenylamine end capping groups were synthesized and
characterized. The photophysical characterization in solution reveals a significant variation in properties
depending on the combined moieties. Amplified spontaneous emission in neat drop cast films of two of
these compounds was studied. One of them was also characterized in terms of its two-photon
photoluminescence.
