抄録

We have synthesized a novel spin crossover Fe<SUP>II</SUP> -triazole complex Fe (AZ-trz), where AZ-trz denotes 4-phenylazo-N-[1, 2, 4]triazole-4-yl-benzamide. <SUP>57</SUP>Fe Mössbauer spectra and magnetic susceptibility measurements of this compound exhibited a gradual spin crossover behavior by thermal change and also a light-induced excited spin state trapping (LIESST) effect. Both UV-visible absorption spectra and IR spectra confirmed the phenomena. The Fe<SUP>II</SUP> high-spin, HS, state was induced by exciting a d-d electronic transition band of the Fe<SUP>II</SUP> low-spin state species. Furthermore, the measurements revealed the lifetime of excited Fe<SUP>II</SUP> HS state to be 1 min.
