Solvothermal reactions of Cd(NO3)2, H3btc, and HBTA afforded a new Cd(II) compound, namely (NH3)2[Cd3(btc)2(BTA)(DMA)]n (1 H3btc = 1,3,5-benzenetricarboxylic acid, HBTA = 1,2,3- benzenetriazole, DMA = N, N′-dimethylacetamide). Single-crystal X-ray analysis reveals that 1 is a complicated three-dimensional (3D) framework based on benzotriazole-controlled trinuclear Cd(II) clusters, which can be simplified into a (3,6)-connected ant-type topological network. Moreover, the luminescent properties of this compound were also investigated at room temperature.

Fluorescent labeling of DNA was studied by using two newly synthesized ligands, which are 4-(2-hydroxybenzylidinamino) benzoic acid (PHBA) and 4-(2-hydroxybenzylidinamino) phthalic acid (PHPA). Their binding capacity to calf-thymus DNA was determined on functionalized superparamagnetic iron oxide nanoparticles (SPIONs). 23.1 µg of DNA was immobilized on 25 mg of nanoparticles. Binding capacity of fluorescent ligands to DNA-APTS-SPIONs was also found as 2.36 µM for PHBA and 1.97 for PHPA at 25 mg of the nanoparticles. Binding of the DNA to the ligands were examined by scanning electron microscopy, transmission electron microscopy, infrared spectroscopy, and confocal microscopy.

In this work CdS nanocrystals (NCs) were synthesized by a simple UV-assisted method. Prepared NCs were characterized by means of XRD, FTIR, TEM, UV-vis, and PL analyses. Synthesized NCs was in hexagonal phase with an average size about 3.5 nm. The NCs bandgap shorten from 3.6 to 3.2 eV only by increasing the illumination from 3 to 12 min. PL spectra showed a white emission and PL peak shifted from near 518 nm to 540 nm by increasing illumination time from 3 to 12 min.

Tetraphenylporphyrin manganese (III) chloride (Mn-TPP) was encapsulated into hexagonal mesoporous silica (HMS) modified by different Lewis acid ions Al, Ti, Zr, and W, which have been tested for selective oxidation of unsaturated olefins and more challenged fatty acid esters under mild condition. Pure W-HMS support displayed no epoxidation activity under the present condition; nonetheless, an unexpected enhanced selectivity for Mn-TPP/W-HMS (90%) with respect to the other samples, especially to homogenous Mn-TPP, indicated the promoted role of W ions over the support. In addition, TG analysis and wetting contact angle measurement were determined in order to reveal the hydrophobic nature of heterogeneous materials, which has been preliminarily scrutinized as the factor influencing catalytic selectivity. That is, Mn-TPP/W-HMS exhibited around 90% selectivity because of a better hydrophobic nature.

A simple method to prepare the Ag porous carbon nanofiber is reported. Ag porous carbon nanofiber was prepared by electrospinning and high temperature calcination. In this process, AgNO3-PMMA/PAN solution was the precursor solution of electrospinning, and Ag nanoparticles and pores were made by high temperature calcination. The catalytic activity of the Ag porous carbon nanofibers was confirmed by the styrene epoxidation. In the catalytic process, the conversation of styrene was 71% and the selectivity of styrene oxide was 83%.
