Synthesis and characterization of amphiphilic triazole ligand and its complex for liquid crystals of phosphorescent temperature sensor materials

Phosphorescent materials have attracted much attention due to their promising applications in sensors, display, optical imaging and drug delivery. Extensive studies have been only reported on the syntheses of trinuclear gold(I) azolate complexes such as imidazolate, pyrazolate and carbeniete. On the...
