1D Chiral Lead Bromide Perovskite with Superior Second-Order Optical Nonlinearity, Photoluminescence, and High-Temperature Reversible Phase Transition.

Multifunctional materials are an attractive research area. Organic-inorganic hybrid perovskites are widely used in the design of these materials due to their rich properties and flexible composition. It is easy to obtain more photoelectric properties by introducing chiral groups as ligands.

Single Crystal to Single Crystal Transformation of Cu Complexes Induced by Dehydrating and Hydrating of Ligands with Chroma Rewritable Behaviors.

In this work, the single crystal to single crystal (SCSC) transformations in three mononuclear copper complexes [Cu]Cl·2HO (), [CuCl] (), and [Cu]Cl·4HO () ( = di-2-pyridyl ketone, = di(pyridin-2-yl)methanediol) are realized by the irreversible dehydration and hydration reaction of and . Dark purple crystal is obtained by self-assembly of and CuCl·2HO in solvothermal reactions, in which the carbonyl group of undergoes a hydration addition reaction to form . On heating, transforms to by dehydrating water accompanied by the change of the color and coordination octahedron of Cu ions.

Two Manganese(II)-Based Hybrid Multifunctional Phase Transition Materials with Strong Photoluminescence, High Quantum Yield, and Switchable Dielectric Properties: (CNH)MnBr and (CNH)MnBr.

Multifunctional materials have always been an attractive research area, but how to combine multiple excellent properties in one compound remains a considerable challenge. Organic-inorganic hybrid compounds are widely used in the design of such materials due to their rich properties and flexible assembly. Herein, two new manganese(II)-based organic-inorganic hybrid compounds, (CNH)MnBr () and (CNH)MnBr (), are prepared by the solution method.
