研究了二芳基乙烯光致变色薄膜的载流子注入和输运特性。二芳基乙烯分子的一种异构化态--闭环结构的存在比例越大，注入和输运的载流子（注入电流）越多。当闭环分子的存在比例为12%时，观察到了显着的增加。降低势垒的效果，这是由Poole-Frenkel-like效应与短距离的相互作用势的空穴传输通过增加闭环分子的存在比例所造成的，提出作为这一现象背后的机制。
Electrical carrier-injection and transport characteristics of photochromic diarylethene thin films were investigated. Injected and transported carriers (injected current) to the diarylethene film were increased with the existence ratio of the closed-ring form, which was one isomerization state of the diarylethene molecule. A dramatic increase was observed at a 12-percent existence ratio of the closed-ring molecules. A lowering effect of the potential barrier, which is caused by a Poole–Frenkel-like effect with a short distance interaction potential for hole transportation by increasing the existence ratio of the closed-ring molecules is proposed as the mechanism behind this phenomenon.
