Abstract

Lanthanide(III) bent-metallocene complexes with a novel photofunctionalized pentamethylcyclopentadienyl ligand having an N-phenylcarbazolyl group (Cp ^PhCar = η⁵-C₅Me₄CH ₂C₁₈H₁₂N), [Ln(Cp^PhCar) 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 Cp^PhCar (ε = 0.88 × 10⁴ M^-1 cm^-1 at 331 nm, Φ = 0.67 at 330 nm excitation, k_r = 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 Cp^PhCar.
