AI 中文摘要
有机表面活性剂在非极性液体中的弱导电特性对许多电流体动力学现象至关重要，支撑着一些前沿技术，尤其是电泳显示器的发展。此前调节这些系统的电性能需改变其组成。本文利用光响应分子通过光照射从外部控制非极性液体中的电现象，使其具有光导性。具体研究了甲苯中的偶氮苯溶液，其导电性可由两种光调节：紫外线诱导反式到顺式异构化，使导电性增加，蓝光触发顺式到反式的逆向异构化，降低导电性。该研究结果为扩展弱导电有机流体的应用提供了新途径，如用于对阳光作出响应的自调节装置或外部可编程显示器。
英文摘要
The weakly conductive properties of mixtures of organic surfactants in nonpolar liquids are fundamental to many electrohydrodynamic phenomena and underpin several cutting-edge technologies, particularly the development of electrophoretic displays. To date, tuning the electrical properties of these systems has involved modifying their composition, including surfactant type and concentration, water content, and the carrier liquid, all of which influence their behavior. Here, we use photoresponsive molecules to control electric phenomena in nonpolar liquids externally with light irradiation, thereby rendering them photoconductive. In particular, we examine azobenzene solutions in toluene, whose conductivity can be adjusted by two colors of light: UV induces trans to cis isomerization, leading to an increase in conductivity, while blue light triggers cis to trans back-isomerization, decreasing conductivity. The findings of this study suggest new ways to expand the applications of weakly conductive organic fluids, such as in self-regulating devices that respond to sunlight or in externally programmable displays.
