Discrete Supertetrahedral Tn Chalcogenido Clusters Synthesized in Ionic Liquids: Crystal Structures and Photocatalytic Activity

Discrete supertetrahedral Tn chalcogenido clusters, which can be regarded as the smallest semiconductor quantum dots with precise chemical composition, have attracted considerable attention due to their outstanding photoluminescent, photoelectric, and photo/electrocatalytic properties. Such discrete molecular clusters are suitable for solution processing towards functional materials and can be used as precursors for constructing open-framework chalcogenides. Traditionally they were synthesized hydro(solvo)thermally with molecular solvents (e. g. water or organic amines), while until recently imidazolium-based ionic liquids (ILs) were found suitable for their preparation acting as reactive solvent and stabilizer for molecular clusters. We discuss herein recent advances in the syntheses, crystal structures, and selected properties of discrete supertetrahedral Tn chalcogenido clusters obtained in ILs. In particular, the enhanced photocatalytic properties of monodispersed Tn clusters in solvents are highlighted.

Ionothermal synthesis of discrete supertetrahedral Tn (n = 4, 5) clusters with tunable components, band gaps, and fluorescence properties

A series of discrete supertetrahedral Tn (n = 4, 5) clusters have been ionothermally synthesized.

PCU-type copper-rich open-framework chalcogenides: pushing up the length limit of the connection mode and the first mixed-metal [Cu7GeSe13] cluster

A pure dimeric connection mode and an unprecedented Cu₇GeSe₁₃ cluster were found in a series of pcu-type copper-rich open-framework chalcogenides.

[Mn2Ga4Sn4S20]8− T3 supertetrahedral nanocluster directed by a series of transition metal complexes

Three new manganese gallium tin sulfides based on T3 supertetrahedral nanocluster of [Mn₂Ga₄Sn₄S₂₀]⁸⁻ have been solvothermally synthesized and structurally characterized. The photocatalytic, second-order nonlinear optical and luminescence properties, as well as thermal stabilities of the title compounds were also studied.

Photo-electroactive ternary chalcogenido-indate-stannates with a unique 2-D porous structure

A series of photo-electroactive 2-D In–Sn–Q ternary compounds are prepared using metal–phenanthroline complex templates. The 2-D network joint of In–Sn–Q is a (In/Sn)₃Q₃ six-membered ring, which is different from the Sn₃S₄ pseudosemicube of most 2-D Sn–Q binary compounds.

Syntheses, structures and photocatalytic properties of five new praseodymium–antimony oxochlorides: from discrete clusters to 3D inorganic–organic hybrid racemic compounds

Presented here are five Pr–Sb–O–Cl cluster-based compounds with structures from discrete organic-decorated cluster to 3D framework that exhibit photocatalytic H₂-evolution activity and magnetic properties.
