Abstract

Lanthanide(III) bent-metallocene complexes with a novel photofunctionalized pentamethylcyclopentadienyl ligand having an N-phenylcarbazolyl group (Cp PhCar = η5-C5Me4CH 2C18H12N), [Ln(CpPhCar) 2I(THF)] (Ln = Tb (1), Gd (2)), were prepared and their molecular structures and luminescence properties were investigated. The f-f emission from the terbium metal center of 1 was efficiently sensitized by CpPhCar (ε = 0.88 × 104 M-1 cm-1 at 331 nm, Φ = 0.67 at 330 nm excitation, kr = 1.68 × 103 s-1). Additionally, the solid-state structure of potassium salts of C5-ring (η5-C5R5, R = Me, H) derivatives was uncommonly characterized in CpPhCar.
