Abstract

original image

Multifunctional Ag@Au@phenol formaldehyde resin (PFR) particles loaded with folic acids (FA) have been designed for killing tumour cells through photothermal conversion under the irradiation of near-infrared light. The multifunctional particles exhibit good fluorescence, low toxicity, and effective targeting for the therapy of tumour cells. Furthermore, the efficiency of photothermal therapy (PTT) and fluorescence intensity can be tuned by simply changing the added amount of HAuCl4. For more details, see the Full Paper by S.-H. Yu et al. on page 9294 ff.

Natural Product Synthesis

The use of ortho-quinone methides in synthesis is increasing year on year. With this growth, the variety of ways in which these intermediates are being generated has also diversified, and it seems unlikely that a single initiation method will emerge as the strategy of choice. See the Minireview on page 9160 ff. by C. D. Bray and N. J. Willis for an up-to- date account on the latest developments in this field of chemistry.

Multifunctional Polyoxometalates

In their Communication on page 9174 ff., summary, Y. Wei, T. Liu et al. show that amphiphilic hybrid hexavanadates are highly efficient emulsion catalysts with high stability for deep oxidation desulfurization. The hybrids can be used as amphiphiles to create emulsions with the catalytically active hexavanadate head-groups distributed at the water–oil interface. The pH of the aqueous phase and the hydrophobicity of alkyl tails on the hybrids both play key roles in controlling the size of emulsion and the formation of reverse emulsions, which consequently determine the reaction rate.

Quantum Dots

In their Full Paper on page 9230 ff. M. Kanehara, T. Teranishi et al. describe a new method for the synthesis of high-quality CdS and Cu7S4 quantum dots (QDs) by using N,N-dibutylthiourea (DBTU) as a sulfur source. The disk-shaped Cu7S4 QDs as schematically shown can be used effectively as templates to form cation-exchanged monodisperse disk-shaped CdS QDs.
