The synthesis and thermotropic liquid crystal (LC) properties of gemini imidazolium salts comprising Cl–, BF–4, PF–6, AuCl–4 counter anions, varied alkenyl spacer lengths and terminal alkyl chains are described. LC properties are investigated by differential scanning calorimetry, polarizing optical microscopy, and powder X-ray diffraction studies. It should be noted that, salts of short spacers favor the formation of mesophase. A SmA with wide mesophase range and high thermal stability are identified. The Cl– salts have shown an odd-even effect on phase transition temperatures as the length and parity of the spacer is varied. The use of [(CH2)4(C18-Im)2][AuCl4]2 salt as precursor for the fabrication of Au nano/micro particles via chem. reduction, photo irradiation, and thermolysis methods is presented. A clear vision of morphol. change is observed in Au structures by varying the reduction method, however the mesophase does not control over the size and morphol. of Au particles in the thermolysis method. The colloidal AuNPs prepared in this study showed remarkable stability for over six months. These results offer great insight into the counter anion and spacer effects on LC nature of gemini Im salts, which broadens the scientific understanding to develop advanced soft materials. In the experiment, the researchers used many compounds, for example, 1-Octyl-1H-imidazole (cas: 21252-69-7Application In Synthesis of 1-Octyl-1H-imidazole).
1-Octyl-1H-imidazole (cas: 21252-69-7) 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. This ring system is present in important biological building blocks, such as histidine and the related hormone histamine.Application In Synthesis of 1-Octyl-1H-imidazole
