Synthesis, crystal structure and photoluminescence of Re(I)2(μ-4,4′-bipyridine)(8-quinolinolato)2(CO)6

Abstract

The binuclear complex Re(I)(2)(mu-4,4'-bipyridine) (8-quinolinolato)(2)(CO)(6) has been prepared and characterized including the crystal structure. This complex shows, dependent on the conditions, three emissions, which originate from the quinolinolate IL excited state (fluorescence and phosphorescence) and from a Re(I) to 4,4'-bipyridine MLCT state (phosphorescence).
