Chemistry is the experimental and theoretical study of materials on their properties at both the macroscopic and microscopic levels.In a patent， HPLC of Formula: C11H8N2O2, Which mentioned a new discovery about 1970-80-5
A 1,3-dipolar cycloaddition reaction of azomethine ylides to C60 has been used to prepare a fulleropyrrolidine covalently linked to a substituted tris(2,2’bipyridine)ruthenium(II) chromophore. Electrochemical studies revealed a single one-electron reversible oxidation of the ruthenium center and ten one-electron reversible reductions, five of them occurring at the C60 core and five at the bipyridine (bpy) ligands. Steady-state fluorescence and time-resolved flash-photolytic investigations of dyad 6 are reported in solvents of different polarity. The emission in toluene/CH2Cl2, CH2Cl2, and CH3CN was substantially quenched, relative to model complex 8, suggesting intramolecular quenching of the ruthenium MLCT excited state. Picosecond-resolved photolysis of 6 showed light-induced formation of the photoexcited ruthenium center, which undergoes rapid intramolecular electron transfer. Nanosecond-resolved photolysis revealed a charge-separated state (tau(1/2)=210 ns in CH2Cl2 and tau(1/2) = 100 ns in CH3CN) that decays to the ground state by regeneration of the ruthenium MLCT excited state in CH2Cl2 or through the formation of the C60 triplet excited state in CH3CN.
I hope this article can help some friends in scientific research. I am very proud of our efforts over the past few months and hope to 1970-80-5, help many people in the next few years.HPLC of Formula: C11H8N2O2
