Abstract: Ruthenium (Ru) complex, are among the most investigated in fields that include solar energy conversion, photocatalysis and molecular recognition, owing to their favorable photophysical and photochemical properties as well as ground state and excited state reactivity. The photo-induced isomerization is one kind of novel reactions for ruthenium complexes, and the study for photo isomerization is of great significance for the light energy conversion, information storage, as well as the design for "molecular switch" and "molecular motor". Herein, the different types, characteristics and mechanism of photo-induced isomerization of ruthenium complexes as well as the recent progress were reviewed.

Key words: ruthenium complexes, photo reaction, geometric isomerism, structural isomerism, excited state, metastable state
