具有光化学和电化学活性的有机分子在功能器件开发方面具有潜在的应用前景 偶氮苯衍生物是典型的化合物之一,如图1A所示,它具有光致顺反异构化和电化学氧化还原反应的双重活性.利用偶氮苯衍生物有序分子组装体系的光电化学性质,我们提出了“单向循环”的新型信息存储原理.在过去的工作中,我们利用Langmuir.Blodgett技术将偶氮苯长链脂肪酸衍生物分子固定在ITO导电玻璃上而形成高度有序的单分子膜.由于偶氮苯衍生物分子是物理吸附在基底上,在反复进行光化学及电化学测试过程中,常常脱落到电解质溶液中,从而造成单分子膜的脱落;同时偶氮苯从反式到顺式过程伴随着空间的增大,因此在致密有序的LB膜中顺反异构化效率较低.我们利用自组装技术将偶氮苯衍生物通过与基底的 Photochemical and electrochemical activity of organic molecules in the development of functional devices has potential applications Azobenzene derivatives is one of the typical compounds, as shown in Figure 1A, it has a photo-cis-isomerization and electrochemical oxidation The dual activity of the reduction reaction.Using the photoelectrochemical properties of ordered molecular assembly system of azobenzene derivatives, we propose a new information storage principle of “one-way circulation.” In the past, we used Langmuir.Blodgett technology to couple even Azobenzene long-chain fatty acid derivative molecules fixed on the ITO conductive glass to form a highly ordered monolayer.As azobenzene derivative molecules are physically adsorbed on the substrate, repeated in the photochemical and electrochemical testing process, often Off into the electrolyte solution, resulting in the monolayer off; while azobenzene from trans to cis with the increase of space, so dense and orderly LB film cis-trans isomerization efficiency is low. We use a self-assembly technique to pass Azobenzene derivatives to the substrate
