One-dimensional organic lead halide perovskites with efficient bluish white-light emission.

ABSTRACT: Organic-inorganic hybrid metal halide perovskites, an emerging class of solution processable photoactive materials, welcome a new member with a one-dimensional structure. Herein we report the synthesis, crystal structure and photophysical properties of one-dimensional organic lead bromide perovskites, C₄N₂H₁₄PbBr₄, in which the edge sharing octahedral lead bromide chains [PbBr₄ ^2-]_∞ are surrounded by the organic cations C₄N₂H₁₄ ²⁺ to form the bulk assembly of core-shell quantum wires. This unique one-dimensional structure enables strong quantum confinement with the formation of self-trapped excited states that give efficient bluish white-light emissions with photolumines
