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 [Au Ag (S-Adm) ] 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 SbF 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.
以纳米团簇/超原子复合物为构建单元制备具有理想性能和增强功能的框架材料,仍然是纳米材料领域的一项挑战。在本研究中,手性[Au Ag (S-Adm) ]纳米团簇/超原子复合物(SC,其中S-Adm = 1-金刚烷硫醇)被用作构建单元,通过无机SbF连接体构建三维(3D)超原子复合物无机框架(SCIF)材料SCIF-1和SCIF-2。由于两种SC对映体在单晶中的组装,SCIF-1是外消旋的。在SCIF-2中,SC对映体被包裹在单独的晶体中,从而产生更大的通道和圆偏振发光(CPL)响应。这两种3D SCIF材料在质子溶剂中表现出独特的灵敏光致发光(PL)。我们的研究为利用超原子复合物制备新型开放框架材料提供了一条新途径,并为用于传感和其他应用的3D框架材料的进一步发展奠定了基础。
