圆偏振发光(CPL)在手性荧光探针,圆偏振有机发光二极管,和光学防伪等领域具有潜在应用,为了扩大CPL材料的应用范围,研究人员开始关注刺激响应型CPL活性材料。胆甾相液晶(CLC)因其高度有序的手性环境以及优异的可调性已成为刺激响应CPL活性材料的理想选择。目前,基于CLC的光响应CPL材料已得到广泛开发,这些材料通常能在多组分系统中实现CPL信号响应。本综述重点关注CLC中光调控CPL的研究进展,总结了CPL调控的三种策略:(1)利用光驱动过程光开关分子的手性或螺旋变化调控CLC的CPL信号;(2)利用手性光开关与手性掺杂剂间手性竞争关系调控CLC的CPL信号;(3)利用光驱动非手性二向色性染料有序参数值变化调控CPL信号。这篇综述有望为基于光响应CLC的CPL调控提供重要的参考和指导,以推动其在更广泛领域的应用。

The properties of liquid-liquid interfaces are intricately linked to its structure, with a particular focus on the concentration distribution within interface. To obtain precise information regarding distribution, we have developed high-resolution soft X-ray imaging method for interfaces. This work focused representative partially miscible systems, analyzing interfacial profiles water-alkanols under both steady-state and dynamic processes, obtaining diffusion coefficients different water concentrations in alkanols. Significant disparities distributions concentration-related were observed despite comparable distances same system across states. Meanwhile, it was found that alkanols exhibit adsorption phenomena at newfound knowledge serves as crucial stepping stone toward deeper understanding systems. Our study opens way explore interface high-resolution.
