Abstract

Organic metal halide hybrids with zero-dimensional (0D) structure at the molecular level, or single-crystalline bulk assemblies of metal halides, are an emerging class of light-emitting materials with high photoluminescence quantum efficiencies (PLQEs) and color tunability. Here we report the synthesis and characterization of a new single-crystalline bulk assembly of metal halide clusters, (bmpy)₉[ZnCl₄]₂[Pb₃Cl₁₁] (bmpy: 1-butyl-1-methylpyrrolidinium), which exhibits green emission peaked at 512 nm with a remarkable near-unity PLQE at room temperature. Detailed structural and photophysical studies suggest that there are two emitting states in [Pb₃Cl₁₁]^5- clusters, whose populations are strongly dependent on the surrounding molecular environment that controls the excited-state structural distortion of [Pb₃Cl₁₁]^5- clusters. High chemical- and photostability have also been demonstrated in this new material.
