units. Starting from this discovery, three dimeric dyes were constructed, and their optical properties were examined. Although the two fluorescent units were orthogonal in each dye, efficient energy transfer was observed in dimeric dye 16 in three solvent systems. In contrast, solvent-dependent energy transfer was detected for another dimeric dye, 5. After close investigation, we found that the orientation
用由2-溴-1,3-二甲基苯和正丁基锂产生的芳基锂试剂处理后,发生甲氧基甲基保护的x吨酮的意外二聚。没有提取两个直接的醚氧原子之间的氢,但是除去了与羰基相邻的氢,得到了包含两个直接连接的荧光fluorescent吨酮和x吨单元的二聚化合物。从这一发现开始,构建了三种二聚体染料,并检查了它们的光学性质。尽管每种染料中两个荧光单元是正交的,但在三种溶剂体系中的二聚体染料16中观察到有效的能量转移。相反,检测到另一种二聚体染料5依赖溶剂的能量转移。经过仔细研究,我们发现取向因子(κ)是影响这些染料中Förster共振能量转移的主要因素。
