During last decade, we have explored the unique photophysical properties of a-cyanostilbene compounds which significantly differ from those of stilbene or azobenzene chromophores. It was found that a-cyanostilbene moiety is an outstanding supramolecular self-assembly motif to give characteristic nanostructures of various dimensionality. Most peculiarly, self-assembly of these molecular motif is accompanied by the significant fluorescence modulation and transport properties. By appropriate molecular design and synthesis, we could also demonstrate supramolecular materials systems which can respond to various external stimuli like the UV, thermal, chemical, and mechanical signals.  I will give a broad overview on this research topic.
