Synthesis and coordination chemistry of 1-(2′,2″-bipyridyl-5′-yl-methyl)-1,4,8,11-tetraazacyclotetradecane L¹. Quenching of fluorescence from [Ru(bipy)₂(L¹)]²⁺ by coordination of Ni^II or Cu^II in the cyclam cavity (bipy = 2,2′-bipyridine; cyclam = 1,4,8,11-tetra-azacyclotetradecane)

Abstract

A novel bipy derivative of cyclam (L¹) designed for controlled and systematic polynuclear metal complex formation is reported; fluorescence quenching of the [Ru(bipy)₃]²⁺ core of [(bipy)₂Ru(L¹)]²⁺ upon coordination of Cu^II at the cyclam cavity is demonstrated.
