We successfully synthesized eight meso-aryl BODIPYs with 2,6-diethyl- or 1,2,6,7-tetraethyl substituents and characterized their photophysical properties. The steric hindrance resulting from the phenolic group in the meso-aryl moiety and the ethyl groups on the BODIPY core affected the synthesis of dipyrromethanes as an intermediate as well as the UV–Vis absorption and fluorescence emission of the
我们成功地合成了8个具有2,6-二乙基或1,2,6,7-四乙基取代基的内消旋芳基BODIPY,并表征了它们的光物理性质。由内消旋芳基部分中的酚基和BODIPY核心上的乙基引起的空间位阻影响了作为中间体的二吡咯甲烷的合成以及BODIPY的UV-Vis吸收和荧光发射,这是由于芳基环。pH依赖性荧光发射也显示出内消旋-羟基苯基BODIPY作为pH传感器的潜在用途。
