摘要

表面配体对金属纳米团簇的光学性质和稳定性有显著影响。本研究合成了[Pt1Ag31(S-Adm)16(DPPM)3(DPPMO)Cl3](SbF6)4 （Pt1Ag31-DPPMO）。与[Pt1Ag31(S-Adm)16(DPPM)3Cl3](SbF6)4 （Pt1Ag31）相比，引入二次膦氧化物配体DPPMO，使得Pt1Ag31-DPPMO在溶液和固体状态下都表现出更强的光致发光性能，并提高了稳定性和吸电子能力。本研究提出了一种新的策略来调节金属纳米团簇的性质，特别是通过加入氧化膦配体来增强其光致发光性能和稳定性。

Enhanced Photoluminescence Emission and Thermal Stability in Pt₁Ag₃₁ nanocluster from Introduced Secondary Phosphine Oxide Functionalized ligand.

Surface ligands significantly influence the optical properties and stability of metal nanoclusters. In this study, we synthesized [Pt₁Ag₃₁(S-Adm)₁₆(DPPM)₃(DPPMO)Cl₃](SbF₆)₄ (Pt₁Ag₃₁-DPPMO). Compared to [Pt₁Ag₃₁(S-Adm)₁₆(DPPM)₃Cl₃](SbF₆)₄ (Pt₁Ag₃₁), the introduction of secondary phosphine oxide ligand, DPPMO, results in Pt₁Ag₃₁-DPPMO exhibiting enhanced photoluminescent properties in both solution and solid states, as well as improved stability and electron-withdrawing ability. This work presents a novel strategy to regulate the properties of metal nanoclusters, especially enhancing photoluminescence performance and stability, through the incorporation of secondary phosphine oxide ligand.

期刊介绍： Chemistry—An Asian Journal is an international high-impact journal for chemistry in its broadest sense. The journal covers all aspects of chemistry from biochemistry through organic and inorganic chemistry to physical chemistry, including interdisciplinary topics. Chemistry—An Asian Journal publishes Full Papers, Communications, and Focus Reviews. A professional editorial team headed by Dr. Theresa Kueckmann and an Editorial Board (headed by Professor Susumu Kitagawa) ensure the highest quality of the peer-review process, the contents and the production of the journal. Chemistry—An Asian Journal is published on behalf of the Asian Chemical Editorial Society (ACES), an association of numerous Asian chemical societies, and supported by the Gesellschaft Deutscher Chemiker (GDCh, German Chemical Society), ChemPubSoc Europe, and the Federation of Asian Chemical Societies (FACS).
