Abstract
Simple oxidation of [Ru(dppcb)(bpy)2](PF6)2 (3) to [Ru(dppcbO2)(bpy)2](PF6)2 (4) switches on the luminescence at ambient temperature, where dppcb and dppcbO2 are cis, trans, cis-1,2,3,4-tetrakis(diphenylphosphino)cyclobutane and cis, trans, cis-1,2-bis(diphenylphosphinoyl)-3,4-bis(diphenyl-phosphino)cyclobutane, respectively. Further enhancing the steric constraints in rac-(ÎÎ/ÎÎ)-[Ru2(dppcb)(bpy)4](PF6)4 (1) and meso-(ÎÎ/ÎÎ)-[Ru2(dppcb)(bpy)4](PF6)4 (2) allows a fine-tuning of the efficiency of luminescence. The X-ray structures of 1-4 explain this effect.
