White-light emission in a chiral one-dimensional organic-inorganic hybrid perovskite

Abstract

Recently, white-light emissions arising from self-trapped excitons in a distorted lattice have attracted remarkable attention in organic-inorganic hybrid perovskites. Although exciton self-trapping reported is easier in lower dimensional structure, one-dimensional organic-inorganic perovskites with white-light emission remain rare. Here, we report a single component white-light emissive hybrid perovskite, C5H14N2PbCl4·H2O (1), which adopts a distinct quantum-wire structure formed by edge-shared highly distorted lead chloride octahedra. Notably, 1 shows a color rendering index as high as 93.9, which almost falls around the highest magnitude for hybrid perovskite white-light emissive materials. In addition, 1 is nonlinear and circular polarized optical active induced by the incoporation of pure enantiomeric organic cation. The combination of white-light emission and chirality may pave an avenue to design new white-light emission organic-inorganic perovskites for multifunctional application.
