A three-dimensional cuprous lead bromide framework with highly efficient and stable thermochromic luminescence properties

Abstract

Herein, by using a structural design strategy of incorporating hetrometallic halide blocks, we prepared the first 3D bimetallic halide of [H₂DABCO]₂Cu₆PbBr₁₂ with new topological network based on two types of 6-connected nodes. Remarkably, this 3D framework displays highly efficient thermochromic luminescence from broadband yellow to green light emissions with remarkable stability.
