Photo-induced long-lived intramolecular electron transfer in a Co valence tautomeric complex
A photo-induced valence tautomerism was observed in a Co complex, [CoIII-LS(phen)(3,5-DBSQ)(3,5-DBCat)]. In this system, visible light illumination induces an electron transfer from 3,5-DBCat to CoIII-LS, producing [CoII-HS(phen)(3,5-DBSQ)(2)]. The resultant photo-induced metastable state could be trapped more than 1 h at 5 K.
