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.

制备了由光致变色二芳基乙烯二硫醇和金纳米粒子组成的网络，并研究了其光化学反应性和电导的光开关。该网络表现出完全可逆的光开关的电导根据二芳基乙烯单元的光致变色反应。这种开关行为归因于分子的π共轭长度的变化。由于高的开关比和良好的可逆性，这种开关系统开辟了复杂的分子电路的可能性。
