在乙腈中，[RuCl2(ppb-etol)(PPh3)] (1, ppb-etol = N-(2-二苯基膦基苯亚甲基)-2-羟基乙胺) 的氯配体被溶剂分子取代，得到 [RuCl(CH3CN)(ppb-etol)(PPh3)]Cl (2) 和[Ru(CH3CN)2(ppb-etol)(PPh3)]Cl2 (3) 在 50°C 避光条件下。该反应伴随着颜色从橙色变为黄色。在紫外-可见光照射下，溶液颜色恢复为橙色，配合物2和3再次转化为配合物1。颜色变化可以重复进行，构建了可逆的光致变色反应体系。
In acetonitrile, the chloro ligands of [RuCl2(ppb-etol)(PPh3)] (1, ppb-etol = N-(2-diphenylphosphinobenzilidene)-2-hydroxyethylamine) are substituted with the solvent molecules to yield an equilibrium mixture of [RuCl(CH3CN)(ppb-etol)(PPh3)]Cl (2) and [Ru(CH3CN)2(ppb-etol)(PPh3)]Cl2 (3) at 50°C in the dark. The reaction is accompanied by a color change from orange to yellow. Upon irradiation of UV-vis light, the color of the solution reverts to orange, and complexes 2 and 3 are converted again into complex 1. The color change can be made repeatedly and a reversible photochromic reaction system is constructed.
