Metal clusters have attracted wide interests due to their unique electronic and optical properties, but the low luminescence quantum yield (QY) prevents them from potential biomedical applications. In this work, silver-doped Au nanoclusters (NCs) are shown to be able to improve the QY of metal clusters. We succeeded in synthesizing ultrabright glutathione (GSH) protected AuAg clusters with 10.8% QY by a one-pot route. Their florescence is about 7.5 times brighter than pure Au NCs, with super photostability and good biocompatibility in physiological environment. Based on density functional theory (DFT) calculations, we investigated the electronic structures and optical properties of the AuAg NCs. The results show that the increase of the density of states of the lowest unoccupied molecular orbital (LUMO) leads to the fluorescence enhancement. In addition, two-photon excitation fluorescence imaging has been performed to show their great potential for biomedicine.

We report, for the first time, a new red-emitting hybrid material based on a single-benzene-based fluorophore (SBBF) and silica. This robust formulation shows several features, including bright emissions at a red wavelength (>600 nm), high scalability (>gram-scale), facile synthesis (one-pot reaction; SBBF formation, hydrolytic condensation, propagation), high stability (under different humidity, pH, light), bio-imaging applicability with low cellular toxicity, and an antibacterial effect within Gram-negative/Gram-positive strains. Based on our findings, we believe that these hybrid materials can pave the way for the further development of dye-hybrid materials and applications in various fields.

A cobalt (Co)/graphene sheets (GRs) composite was synthesized via a one-pot chemical method. The composite shows high saturation magnetizations (Ms), which leads it to be conveniently separated from aqueous solution by an external magnetic field. Compared to the pure Co and some references, the catalytic activity of the as-obtained composite was significantly enhanced for the generation of H2 gas by hydrolysis of NaBH4 solution. Effects of NaBH4 initial concentration, the composite and reaction temperature on the H2 generation rate were investigated. The H2 generation rate is independent with the initial NaBH4 concentration, increased with the reaction temperature increasing. The composite can be continuously used several times with about the same catalytic activity.

Synthetic Transformations

The reagent system comprised of halotrimethylsilane and nitrite or nitrate salts has now been successfully used as an efficient system for a series of versatile synthetic transformations. In recent years, the significance and efficacy of this system for reactions such as nitration of aromatics and olefins, oxidation of thiols to sulfonyl chlorides, ipso-nitrosation/nitration of arylboronic acids, ipso-nitration of α,β-unsaturated carboxylic acids to nitro olefins, etc. have been disclosed. Though the reagent system has not been exploited to its full potential, the reported reactions reveal its advantages as a very safe and convenient system that works under mild conditions. This brief Account reveals various synthetic applications of halotrimethylsilane-nitrite/nitrate salts in organic synthesis hitherto reported.1 Introduction2 Reactions Using a Halotrimethylsilane-Nitrate Salt System2.1 Nitration of Olefins and Aromatics2.2 One-Pot Preparation of gem-Chloronitroso, gem-Chloronitro, and vic-Dichloro Compounds2.3 One-Step Conversion of Anilines into Haloarenes2.4 Deoximation of Aldoximes to Aldehydes and Ketoximes to ­Ketones2.5 One-Pot Synthesis of Cyclic/Noncyclic α-Nitroketones from ­Cyclic/Noncyclic Olefins2.6 ipso-Nitration of Arylboronic Acids2.7 ipso-Nitrosation of Arylboronic Acids2.8 Oxidation of Sulfides and Sulfoxides to Sulfones2.9 Oxidative Chlorination of Thiols and Disulfides to Sulfonyl ­Chlorides2.10 α-Halogenation of Carbonyl Compounds2.11 Decarboxylative ipso-Nitration and Dibromination of Cinnamic Acid3 Conclusion
