Herein the synthesis, spectroscopic characterization, two‐photon absorption and electrochemical properties of 3,6‐disubstituted carbazole tweezers is reported. A dimer resulting from a Glaser homocoupling was isolated during a Sonogashira coupling reaction between a diethynyl‐carbazole spacer and a 5‐bromo‐triarylporphyrin and the properties of this original compound were compared with the 3,6‐disubstituted
本文报道了3,6-二取代咔唑镊子的合成,光谱表征,双光子吸收和电化学性质。在二乙炔基-咔唑间隔基和5-溴-三芳基卟啉之间的Sonogashira偶联反应过程中,分离了Glaser偶合产生的二聚体,并将该原始化合物的性质与3,6-二取代咔唑双卟啉镊子进行了比较。本文报道的二元组在920 nm处具有最大的两个光子吸收,且两个光子的吸收截面在1200 GM范围内。尽管在Soret区有很强的线性吸收和适度的荧光量子产率,但它们均导致达到30 000 M -1 cm -1的高亮度 。
