Most of the compounds have physiologically active properties, and their biological properties are often attributed to the heteroatoms contained in their molecules, and most of these heteroatoms also appear in cyclic structures. A Journal, European Journal of Inorganic Chemistry called A Luminescent Rhenium(I) Metallacycle with Oxygen and Nitrogen Donor Atoms: Photophysical and Theoretical Studies, Author is Bhattacharya, Dibyendu, which mentions a compound: 1194-22-5, SMILESS is CC1=NC(=CC(N1)=O)O, Molecular C5H6N2O2, Quality Control of 6-Hydroxy-2-methylpyrimidin-4(3H)-one.
A new N,O-bischelator-bridged dirhenium(I) metallacycle, [Re2(CO)6(μ-η4-mpdo)(dpe)] (1, H2mpdo = 2-methylpyrimidine-4,6-diol, dpe = 1,2-di-4-pyridylethane) was self-assembled in a one-pot reaction in p-xylene at 140°. Compound 1 displays unusual multiple phosphorescence emissions at room temperature; an emission quantum yield of 0.26 ± 0.03 and triexponential decay with an average radiative decay constant of 0.052 μs (λmax = 342 nm) were determined These results as well as those of DFT/TDDFT calculations confirmed the nature of the emitting states.
As far as I know, this compound(1194-22-5)Quality Control of 6-Hydroxy-2-methylpyrimidin-4(3H)-one can be applied in many ways, which is helpful for the development of experiments. Therefore many people are doing relevant researches.
