Abstract
The atomic precision of metal nanoclusters and variability of surface ligands pave the way for their rational design and functionalization, whereas the property strengthening in multiple ways has been long challenging. Herein, improved amphiphilicity, chirality, thermostability, and strong CPL (circularly polarized luminescence) properties have been accomplished by facile ligand exchange of [Au23(CHT)16]- with HCapt (HCHT and HCapt denote cyclohexanethiol and captopril). In addition, the obtained chiral [Au23(SR)16]- (short for [Au23(CHT)16-x(Capt)x]-) clusters show specific binding affinity to remote-diamines (such as arginine and single/double strand DNA), originating from the hydrogen bonding and Van der Waals interaction among the surface Capt ligands and the di-amine groups.
期刊介绍：
Chemistry—A European Journal is a truly international journal with top quality contributions (2018 ISI Impact Factor: 5.16). It publishes a wide range of outstanding Reviews, Minireviews, Concepts, Full Papers, and Communications from all areas of chemistry and related fields.
Based in Europe Chemistry—A European Journal provides an excellent platform for increasing the visibility of European chemistry as well as for featuring the best research from authors from around the world.
All manuscripts are peer-reviewed, and electronic processing ensures accurate reproduction of text and data, plus short publication times.
The Concepts section provides nonspecialist readers with a useful conceptual guide to unfamiliar areas and experts with new angles on familiar problems.
Chemistry—A European Journal is published on behalf of ChemPubSoc Europe, a group of 16 national chemical societies from within Europe, and supported by the Asian Chemical Editorial Societies. The ChemPubSoc Europe family comprises: Angewandte Chemie, Chemistry—A European Journal, European Journal of Organic Chemistry, European Journal of Inorganic Chemistry, ChemPhysChem, ChemBioChem, ChemMedChem, ChemCatChem, ChemSusChem, ChemPlusChem, ChemElectroChem, and ChemistryOpen.
