spectral characteristics, photostability and thermal degradation of B(III) and Zn(II) complexes with 3,3′,5,5′-tetramethyl-2,2′-dipyrromethene and meso-phenyl-3,3',5,5′-tetramethyl-2,2′-dipyrromethene were presented. It has been shown that meso-phenyl substitution in the 3,3′, 5,5′-tetramethyl-2,2′-dipyrromethene complexes with B(III) and Zn(II) leads to a hypsochromic displacement S0 → S1 bands in the EAS
摘要 3,3',5,5'-四甲基-2,2'-二吡咯亚甲基和meso-phenyl-3的B(III)和Zn(II)配合物的光谱特性、光稳定性和热降解研究结果,3',5,5'-四甲基-2,2'-二吡咯亚甲基被提出。已经表明,与 B(III) 和 Zn(II) 的 3,3', 5,5'-四甲基-2,2'-二吡咯亚甲基复合物中的中苯基取代导致在EAS 及其强度显着增加,但荧光量子产率下降。已经确定,在中间位置引入苯基取代基会增加热稳定性(Bodipy 高达 20°C,Zn 配合物高达 74°C)和光稳定性(Bodipy 和Zn(II) dipyrromethenates 高达 7 倍)。
