摘要

对于大多数金纳米团簇(NCs)来说,其水溶性、低光致发光强度和光稳定性是限制其在生物医学和光催化领域应用的三个关键因素。在这项研究中,我们报告了一种聚合物包裹方法,用于将有机可溶性NCs相转移到水相中,而不会降低其电子和光学性能,并且这种材料在水中具有强大的光催化作用。我们首先合成了Au18(DMBT)14 NC (DMBT = 2,4-二甲基苯乙酯),并发现与Au18(CHT)14对应物(CHT =环己硫酯)相比,芳香族配体赋予NC的抗氧化能力大大增强,并通过x射线晶体学鉴定了芳香族配体相互作用的关键作用。有机可溶性Au18(DMBT)14通过两亲性聚合物(Pluronic F127,简称:Pluronic F127)成功转移到水相中。F127)包裹法,产生Au18-D@F127纳米颗粒[每个含有少量nc;Au18- d是Au18(DMBT)14的缩写,其PL强度增强了10倍,Au18(CHT)14也得到了类似的结果。该方法广泛适用于各种NCs,使其具有水溶性,并显著提高了弱发射金NCs的PL强度。Au18(DMBT)14优异的抗氧化稳定性使Au18-D@F127 NPs能够有效地用于过硫酸盐的光催化活化和随后的水污染物的光降解。

Generalizable Organic-to-Aqueous Phase Transfer of a Au18 Nanocluster with Luminescence Enhancement and Robust Photocatalysis in Water

For the majority of gold nanoclusters (NCs), their water insolubility, low photoluminescence (PL) intensity, and less understood photostability are three critical factors that limit their application in the biomedical and photocatalysis fields. In this study, we report a polymer wrapping method for phase transfer of organic soluble NCs into aqueous phase without degrading the electronic and optical properties, and such materials are further demonstrated for robust photocatalysis in water. We first synthesized a Au18(DMBT)14 NC (DMBT = 2,4-dimethylbenzenethiolate) and found that the aromatic ligands confer a greatly enhanced antioxidation capability of the NC compared to the Au18(CHT)14 counterpart (CHT = cyclohexanethiolate), with the critical role of aromatic ligand interactions identified by X-ray crystallography. The organic soluble Au18(DMBT)14 was successfully transferred into the aqueous phase by an amphiphilic polymer (Pluronic F127, abbrev. F127) wrapping method, producing Au18-D@F127 nanoparticles [each containing a few NCs; Au18-D is an abbreviation for Au18(DMBT)14] with a 10-fold enhancement in PL intensity, and similar results were also obtained for Au18(CHT)14. This method is broadly applicable to various NCs, rendering their water solubility and significantly enhancing the PL intensity of otherwise weakly emissive gold NCs. The exceptional antioxidation stability of Au18(DMBT)14 enables the application of Au18-D@F127 NPs for the photocatalytic activation of persulfate ions and subsequent photodegradation of water pollutants efficiently.
