Modelling the luminescence of extended solids: an example of a highly luminescent MCM-41 impregnated with a Eu3+ beta-diketonate complex. Abstract A regular MCM-41 type mesostructured silica was used as a support for the incorporation of the highly luminescent tris(β-diketonate) complex Eu(tta)3ephen yielding the hybrid MCM–Eu material. Suitable characterization by powder X-ray diffraction (XRD), thermogravimetric analyses…

Effect of the Cation on the Interactions between Alkyl Methyl Imidazolium Chloride Ionic Liquids and Water. Abstract A systematic study of the interactions between water and alkyl methyl imidazolium chloride ionic liquids at 298.2 K, based on activity coefficients estimated from water activity measurements in the entire solubility range, is presented. The results show that…

Synthesis, Structural Elucidation, and Catalytic Properties in Olefin Epoxidation of the Polymeric Hybrid Material [Mo3O9(2-[3(5)-Pyrazolyl]pyridine)](n) Abstract The reaction of [MoO2Cl2(pzpy)] (1) (pzpy = 2-[3(5)-pyrazolyl]pyridine) with water in an open reflux system (16 h), in a microwave synthesis system (120 °C, 2 h), or in a Teflon-lined stainless steel digestion bomb (100 °C, 19 h) gave…

Intermolecular C–H···O interactions in cyclopentanone: an inelastic neutron scattering study. Abstract The inelastic neutron scattering (INS) spectra of cyclopentanone were obtained for pure and 50% CCl4 solution forms. Spectra are compared with infrared and Raman data, and with DFT calculated eigenvectors. This exercise aims to find spectroscopic evidence in the neutron spectra for the presence…
