Comprehensive Summary

Metal clusters with photoswitching ligands can undergo magnetic changes under light radiation, which makes them potential optical-response magnetic-switching materials. Herein, a photoswitchable Mn-oxo cluster [MnII15MnIII4(L)18(OH)12(N3)6] (ClO4)2 (C6H5CN)8, (Mn19azo, HL=1-(hydroxymethyl)-3,5-dimethyl-4-(phenyldiazenyl)-pyrazole) has been designed and synthesized to realize the photoswitching behavior. Mn19azo shows quick trans-to-cis transformation upon 365 nm light irradiation in CH2Cl2 solution and solid state as confirmed by UV-Vis spectra. After the powder sample was irradiated for 80 min, the Curie constant of Mn19azo increases by about 7%. The change of magnetic properties can be considered as the result of the change of intermolecular interactions.image
