Vermiculite clays were leached with HNO3 and functionalized with (3-chloropropyl)trimethoxysilane. The resulting materials were modified with the methylimidazolium (MID) group to yield cationic surfaces. These materials were characterized by IR spectroscopy, elemental analyses, and sp. surface area. Tetrakis(尾-diketonate)europate(III) complexes, [EuL4]– [L = dibenzoylmethane (DBM) and thenoyltrifluoroacetone (TTA)], were immobilized on the vermiculite surface containing the imidazolium cation to yield hybrid surfaces named Vx-MID-EuL4 (x = 0, 1, and 2), in which x represents the nitric acid concentration in mol L-1 that was used in the leaching process. The highest luminescence intensities of the intraconfigurational-4f 5D0鈫?sup>7FJ transitions (for which J = 0, 1, 2, 3, and 4) arising from [EuL4]– complexes were presented by the hybrid materials containing the amount of imidazolium cation, which depend on the leaching process. The excitation and emission spectra suggested an efficient intramol. energy-transfer process from ligand-to-Eu3+ ion in the supported materials. The photoluminescent properties of the hybrid materials were studied based on the emission quantum efficiency (畏), exptl. intensity parameters 惟2 and 惟4, and Einstein’s emission coefficient (A0J). The values of these parameters for the V2-MID-EuL4 surface are close to those assigned to the [EuL4]– isolated complexes, which indicates that hybrid vermiculite materials are promising red phosphors. In the experiment, the researchers used many compounds, for example, 1-Methyl-1H-imidazol-3-ium chloride (cas: 35487-17-3Application In Synthesis of 1-Methyl-1H-imidazol-3-ium chloride).
1-Methyl-1H-imidazol-3-ium chloride (cas: 35487-17-3) belongs to imidazole derivatives. Among the different heterocyclic compounds, imidazole is better known due to its broad range of chemical and biological properties. Imidazole has become an important synthon in the development of new drugs. Imidazole also acts as a microtubule destabilizing agents and inhibits topoisomerase and Cytochrome P450 Family 26 Subfamily A Member 1 (CYP26A1) enzymes.Application In Synthesis of 1-Methyl-1H-imidazol-3-ium chloride
