Abstract

A series of new regioregular polyaryleneethynylene obtained by condensation of 3-hexyl multisubstituted oligothiophene derivatives with benzene and anthracene compounds were prepared. A complete NMR characterization of the starting monomers and model compounds lead to a deep investigation of the corresponding macromolecules. Both small and large molecules were optically characterized, the former, particularly when containing anthracene, moieties display noticeable photoluminescence quantum yield. In the polymers the photoluminescence quantum yield is lower than that of the starting molecules when anthracene is present, while the polymers containing benzene are more luminescent.
