Ag(I) complex design affording intense phosphorescence with landmarking lifetime of over 100 milliseconds

Abstract

A highly emissive Ag(I) complex comprising 2,9-dimethyl-1,10-phenanthroline (dmp) and bis[(2-diphenylphosphino)phenyl] ether (dpep) ligands has been synthesized, characterized and investigated for photophysical properties both experimentally and theoretically. The material exhibits an intense phosphorescence from the triplet state of ligand centered (3LC) character featuring the unprecedentedly long lifetime of τ = 110 ms at a quantum yield of ΦPL = 50 % as measured for a doped PMMA matrix under ambient conditions. This is an efficient yet landmarkingly slow emission decay breaking the previous record by orders of magnitude. Such properties are due to the Ag(I) ion, ensuring some weak spin-orbit coupling and an efficient population of the emitting triplet state, and due to a rigid molecular design that combined with a matrix-based rigidity largely suppresses non-radiative relaxations.
