title: From T2,2@Bmmim to Alkali@T2,2@Bmmim Ivory Ball-like Clusters: Ionothermal Syntheses, Precise Doping, and Photocatalytic Properties.
abstract: Presented here are the syntheses, structures, and properties of an In-Sn-Se compound based on a ternary super-supertetrahedral T2,2 cluster nested by Bmmim cations and two of its alkali-doped quaternary analogues. By means of a one-pot ionothermal method, an alkali metal ion (Cs(+) or Rb(+)) could be precisely doped into the central cavity of the cluster, forming an alkali@T2,2@Bmmim quaternary cluster. Remarkably, the undoped compound exhibited excellent stability and visible light photodegradation ability over a wide range of pH, especially in acidic conditions.
