Abstract

The invention provides perovskite-type lead-halide-based organic-inorganic hybridized molecular machines containing crown ether and a production method and application thereof. The molecular machineshave a chemical general formula of (ABPbX2Y)n, wherein A is monovalent cation, B is crown ether, X and Y refer to halogen anions, n represents the number of repeat units and is equal to mNA, with m>0,and NA is Avogadro's constant. The crown ether is introduced to complex with the monovalent cation, the halogen anions for balancing the monovalent cation may coordinate with lead halide, such that inorganic component [Pb(X2Y)-]n and organic component [(AB)+]n are connected and assembled via Y-A bond; as atomic positions of C and O in the crown ether change constantly, the disordered structure enables [(AB)+]n to constantly rotate around [Pb(X2Y)-]n, and a series of perovskite-type lead-halide-based organic-inorganic hybridized molecular machines are obtained. The molecular machines may alsoact as dielectric materials, light-emitting materials, ferroelectric materials and / or photocatalytic materials.

Description

technical field [0001] The invention belongs to the technical field of three-dimensional nanometer materials, and in particular relates to a perovskite-type lead halide-based organic-inorganic hybrid molecular machine containing a crown ether, a preparation method and an application thereof. Background technique [0002] Perovskite originally refers to CaTiO discovered by German geologist Gustav Rose in 1839 3 , he named it after the Russian geologist Perovski, and it was gradually used to refer to compounds with perovskite structure types. The most basic structure of organic-inorganic hybrid perovskite is ABX 3 , B ions and X ions can form a more perfect regular octahedron [BX 6 ] 4- , the octahedron and the octahedron are directly connected to the top and extend infinitely to form a three-dimensional framework, and the A ions are filled in the gaps formed by the regular octahedron. In the hybrid perovskite structure, B ions generally refer to metal cations, and the com...
