Abstract

Here we report the synthesis and crystallization of a -COOH-capped -heterocyclic carbene (NHC)-protected Au cluster. The single-crystal structure of the -COOH-capped NHC-Au cluster reveals a classic icosahedral core with one Au atom in its center. The icosahedral core is surrounded by five NHC ligands with pseudo C5 symmetry and exposed carboxyls in a pentagonal antiprism fashion. The detailed formula of the Au cluster was identified as Au(bi-NHC carboxyl)Cl (hereafter abbreviated as Au-c). The density functional theory (DFT) calculations confirm that Au-c is an electronically stable eight-electron super-atom cluster and elucidate its optical transitions in the UV-Vis range. The Au-c cluster exhibits excellent thermal and chemical stability under bio-relevant conditions. Additionally, this cluster shows a strong red emission in DMF and HO with an excellent quantum yield (QY) of 40% and 12.6%, respectively. The high QY of Au-c enables its use in cell imaging on both cancer and noncancerous cells.

摘要

在此，我们报道了一种羧基封端的杂环卡宾（NHC）保护的金簇的合成与结晶。羧基封端的NHC-金簇的单晶结构揭示了一个经典的二十面体核心，其中心有一个金原子。二十面体核心被五个具有伪C5对称性的NHC配体包围，并以五角反棱柱的方式暴露羧基。金簇的详细化学式被确定为Au(bi-NHC羧基)Cl（以下简称为Au-c）。密度泛函理论（DFT）计算证实Au-c是一种电子稳定的八电子超原子簇，并阐明了其在紫外-可见范围内的光学跃迁。Au-c簇在生物相关条件下表现出优异的热稳定性和化学稳定性。此外，该簇在DMF和水中分别表现出强烈的红色发射，量子产率（QY）分别高达40%和12.6%。Au-c的高量子产率使其能够用于癌症和非癌细胞的细胞成像。
