fac-Tricarbonyl rhenium(I) complexes of triazole-based ligands: Synthesis, X-ray structure and luminescent properties

New tricarbonyl rhenium(I) complexes with 5-phenyl-3-(pyridin-2-yl)-1,2,4-triazole and its derivatives were obtained. Photophysical studies showed that this compounds have good for visualization fluorescent properties i.e., high intensity of the luminescence signal, large Stokes shifts, and long lifetimes of the luminescence. 71
