| Research Abstract |
The networks composed of photochromic diarylethene dithiols and gold nanoparticles were prepared, and the photochemical reactivity and photoswitching of the conductance were studied. The networks showed a completely reversible photoswitching of the conductance according to the photochromic reactions of the diarylethene units. The switching behavior is attributed to the change of the π-conjugation length of the molecule. Because of the high switching ratio and good reversibility this switching system opens up the possibility of sophisticated molecular electric circuits.
