It is quite challenging to investigate the dynamics of coordination-driven self-assembly due to the existence of multiple intermediates and many possible processes. By taking advantage of the high sensitivity and efficiency of fluorescence-resonance energy transfer (FRET), FRET was successfully employed to real-time monitor the dynamic behavior of coordination-driven self-assembly. The Förster energy transfer efficiencies and kinetic aspects of a series of discrete, well-defined metallacycles have been determined. Moreover, the dynamic characteristics of these supramolecular assemblies, such as the dynamic ligand exchange, anion-induced disassembly and reassembly, and stability in different solvents, have been investigated by using FRET.
由于存在多种中间体和许多可能的过程，研究配位驱动自组装的动力学具有相当大的挑战性。利用荧光共振能量转移（FRET）的高灵敏度和高效率，成功地将 FRET 用于实时监测配位驱动自组装的动态行为。确定了一系列离散的、定义明确的金属环的福斯特能量转移效率和动力学方面。此外，通过使用 FRET 研究了这些超分子组装体的动态特性，例如动态配体交换、阴离子诱导的解体和重组以及在不同溶剂中的稳定性。
