Azobenzene derivatives are well-known for their photoisomerization. Due to E-Z isomerization, azobenzene derivatives are seldom fluorescent, which hinders their high-tech applications. Herein, we report two azobenzene derivatives, TPE-Azo-OH and TPE-Azo-2OH, with photoisomerization properties and solid-state fluorescence. Theoretical investigations revealed that the unusual fluorescence contributed
偶氮苯衍生物因其光致异构作用而闻名。由于E - Z异构化,偶氮苯衍生物很少发出荧光,这阻碍了其高科技应用。在此,我们报道了两种偶氮苯衍生物,TPE-Azo-OH和TPE-Azo-2OH,具有光致异构化特性和固态荧光。理论研究表明,异常荧光是由S 2 (π, π*) 通过固态状态混合产生的。由于分子内氢键抑制光异构化,TPE-Azo-2OH 表现出更强的荧光。此外,还原后,这些偶氮苯衍生物表现出从红色到绿色的荧光转变。这些具有AIE属性和刺激响应性的新型偶氮苯衍生物有望为开发光响应发光材料提供新的平台。
