Homochiral Hybrid Organic-Inorganic Cadmium Chlorides Directed by Enantiopure Amino Acids.

Homochiral cadmium chlorides were prepared under mild conditions using enantiopure amino acids as structure-directing agents. They feature a lacunary hexagonal CdCl lattice as well as a one-dimensional perovskite structure. The coexistence of protonated and zwitterionic amino acids between cadmium chloride chains is quite rare.

Amino acid-templated zinc phosphites: low-dimensional structures, fluorescence, and nonlinear optical properties.

Two new zinc phosphites were prepared using the amino acid alanine as a structure-directing agent. They have tubular and ladder-like structures, exhibiting blue fluorescence upon UV light irradiation. Notably, the tubular structure is unprecedented in metal phosphite systems.

Pillared-layered indium phosphites templated by amino acids: isoreticular structures, water stability, and fluorescence.

Two crystalline open-framework indium phosphites (denoted SCU-31 and SCU-32) were prepared using amino acids as structure-directing agents. They have isoreticular pillared-layered structures built up from 6 × 1 and 4 = 1 clusters. Notably, the two compounds show excellent water stability and exhibit blue fluorescence under UV light irradiation at room temperature.

Two low-dimensional metal halides: ionothermal synthesis, photoluminescence, and nonlinear optical properties.

Two new organic-inorganic hybrid metal halides, formulated as (C7H13N2)2MnCl4 (1) and (C6H11N2)PbBr3 (2), were prepared by a two-component ionothermal approach using multifunctional ionic liquids as solvents, charge-balancing agents, and halide sources. Compound 1 has an ionic zero-dimensional structure showing bright green luminescence with a high quantum yield of up to 70.78%.
