Prolonged luminescence lifetimes of Ru(ii) complexes via the multichromophore approach: the excited-state storage element can be on a ligand not involved in the MLCT emitting state†
Abstract
A novel series of ruthenium terpyridine complexes with bichromophoric units separated by more than 1 nm display an extraordinary enhancement of their luminescence lifetimes when compared to the parent Ru(tpy)22+
