A series of dimethyldihydropyrene-appended metal complexes has been synthesized and thoroughly characterized using electrochem. and spectroscopic methods. The ring-opening reaction undergone by the dimethyldihydropyrene core under visible light irradn. proceeds much more efficiently when the metal complexes and the photochromic moiety are connected through a pyridinium-bridge vs a Ph bridge. The clean electrochem. and photochem. responses of these hybrid systems make them good candidates for the conception of new multi-addressable photo- and redox-switches. [on SciFinder(R)]
