Abstract:	Due to their promising photoelectronic features, 2D-Germanane (2D-GeH) and their ligand-terminated derivatives (2D-GeR) have garnered significant attention in the Materials Science community. To date, the synthesis of 2D-GeR relies on a tedious topochemical reaction, a fact that not only limits the variety of R ligands that can be incorporated but also restricts their stability and applicability. Herein, a highly stable carbohydrate-based 2D germanane derivative with built-in stereodiscrimination ability has been synthesized via a direct covalent immobilization of a cyclic oligosaccharide selector (viz. thiolated β-cyclodextrin, CD-SH) onto 2D-GeH. By taking advantage of the CD affinity to accommodate different stereoisomers through supramolecular host-guest interactions, the multitasking activity of the resulting 2D-GeCD has been explored for the selective discrimination of enantiomers and diastereomers. Overall, this chemical approach is general and opens up the development of multitasking 2D-GeR derivatives by incorporating supramolecular features, which can be easily extended to a wide range of bio-molecules by tailoring the stereometric host-guest encapsulation.
