文摘

In the [Er(hfac)₃(L)]₂ complex (1) (L = 4-tetrathiafulvalene-2,6-pyridinecarboxylic acid dimethyl ester), the Er(III) ion is bonded to the tridentate coordination site. Electrochemical and photophysical measurements in solution reveal that the tetrathiafulvalene moiety is a versatile antenna for erbium luminescence sensitization at 6540 cm^鈥? upon excitation in the low-energy charge transfer transition (donor to acceptor charge transfer) at 16600 cm^鈥? assigned via time-dependent density functional theory calculations.
