Two novel metal-free organicdyes containing thienothiophene and thiophene segments have been synthesized. Nano-crystalline TiO2 dye-sensitizedsolarcells were fabricated using these dyes as light-harvesting sensitizers, and a high solar energy-to-electricity conversion efficiency of 6.23% was achieved.

Experimentally measured second-ordernonlinear hyperpolarizability (βµ) data for a new series of donor-acceptor conjugated compounds containing tricyanovinyl acceptors and thiophene conjugating units, reveal that this combination results in a dramatic enhancement (αµ= 6000–9000 × 10–48 esu) of their molecular nonlinearity.

Second order molecular nonlinear optical properties of push-pull stilbenes can be substantially increased by replacing benzene rings with thiophene rings. Synthesis and molecular nonlinear optical properties of several dialkylamino-nitro substituted thiophene based stilbenes are presented.
