three carbon atoms were prepared, and intramolecular excimer formation was investigated. All rate constants in Forster’s kinetics were determined by the steady state and time-resolved fluorescence measurements. A large difference in the association rate constant was observed with variation of molecular structure. The results suggest that intramolecular excimer formation is directly controlled by the rotational
制备了两个萘基被三个碳原子隔开的各种二萘基烷烃,并研究了分子内准分子的形成。Forster 动力学中的所有速率常数均由稳态和时间分辨荧光测量确定。随着分子结构的变化,观察到缔合速率常数的巨大差异。结果表明,分子内准分子的形成直接受分子从相邻构象到准分子构象的旋转弛豫过程控制。观察到内消旋-2,4-二萘基戊烷的形成速率很大(25°C 时为 7.9×108 s-1),发现外消旋异构体的速率是内消旋异构体的十分之一。
