文摘

A series of dinuclear metal terpyridine (M-tpy; M = Ru, Os, Fe,and Co) complexes with a photochromic dithienylethene bridgewere designed and synthesized through either a convergent or adivergent approach. The open forms of the complexes containingRu^II and Fe^II centers were found to be inert to ultravioletphotoirradiation but could be cyclized electrochemically as revealedby a cyclic voltammetric study. On the contrary, the Co^II complexunderwent efficient photochemical but not electrochemical cyclization. The corresponding Os^II complex was neither photochromicnor electrochromic.
