Abstract

Abstract: Building framework materials with desirable properties and enhanced functionalities with nanocluster/superatom complexes as building blocks remains a challenge in the field of nanomaterials. In this study, the chiral [Au1 Ag22 (S‐Adm)12 ] 3+ nanocluster/superatom complex (SC, in which S‐Adm=1‐adamantanethiol) was employed as a building block to construct the three‐dimensional (3D) superatom complex inorganic framework (SCIF) materials SCIF‐1 and SCIF‐2 through inorganic SbF6 − linkers. SCIF‐1 is racemic due to the assembly of two SC enantiomers in a single crystal. In SCIF‐2, the SC enantiomers are packed in separate crystals, thus producing larger channels and a circularly polarized luminescence (CPL) response. These two 3D SCIF materials exhibit unique sensitive photoluminescence (PL) in protic solvents. Our study provides a new pathway for creating novel open‐framework materials with superatom complexes and a foundation for the further development of 3D framework materials for sensing and other applications. Abstract : A fresh framework : A new type of porous material, termed a SCIF (superatom complex inorganic framework), was constructed by linking Au1 Ag22 superatom clusters with inorganic SbF6 − (see picture). The obtained SCIF‐1 and SCIF‐2 materials exhibited unique fluorescence and circularly polarized luminescence properties.
