本文测定了能够给出有关~1(1,1′-BIN)~*构型变化信息的1,1′-BIN和其他一些化合物在不同溶剂中的荧光寿命和发射光谱,并研究了1,1′-BIN激发电荷转移的性质。其结果表明,在激发的双萘分子中的两个萘基在流体溶剂中于室温时绕c—C连键的旋转是非常快的,即使在粘度很大的溶剂中在280PS之内都观测不到它的构型变化。其荧光发射谱带证明~1(1,1′-BIN)~*构型与“两个萘基”共平面的~1(DBF)~*和~1(BOHF)~*的构型不同。1,1′-BIN与N-丙基-2,5-二甲基吡咯(PDMP)之间形成了激发络合物。测得了~1(1,1′-BIN)~*的荧光衰变函数。
In this paper, the fluorescence lifetime and emission spectra of 1,1’-BIN and other compounds that can give information about the configuration changes of ~1 (1,1’-BIN) ~ * were determined. 1’-BIN initiates the property of charge transfer. The results show that the rotation of the two naphthyl groups in the excited dinaphthyl molecule around the c-C linkage in the fluid solvent at room temperature is very fast even within 280 PS in a very viscous solvent Not its configuration changes. Their fluorescence emission bands demonstrate ~ 1 (1,1’-BIN) ~ * configuration is different from the configuration of ~1 (DBF) ~ * and ~1 (BOHF) ~ * of the “two naphthyl” Excimer complexes formed between 1,1’-BIN and N-propyl-2,5-dimethylpyrrole (PDMP). The fluorescence decay function of ~ 1 (1,1’-BIN) ~ * was measured.
