Abstract

Abstract : A novel emissive tetranuclear Ag(i ) complex with highly efficient thermally activated delayed fluorescence (TADF) was successfully prepared and characterized. The significant participation of a metal orbital in the occupied frontier orbitals leads to dominant MLCT emission. Abstract : A novel tetranuclear Ag(i ) complex, [Ag4 (μ-DMPTP)2 (POP)3 ][BF4 ]2 (Ag4 N2 P3 ), has been designed to achieve highly efficient thermally activated delayed fluorescence (TADF). Photophysical investigations show that the compound exhibits highly efficient TADF ( Φ = 76%) and has a very short ambient-temperature TADF decay time of only 0.65 μs, corresponding to a radiative decay rate of k = Φ / τ = 1.2 × 10 6 s −1, a value belonging to the fast radiative rates in TADF materials.
