Quenching of the Fluorescence of a Coumarin Derivative by Aromatic Amines
The effect of three aromatic amines namely aniline (AN), dimethyl aniline (DMAN) and diethyl aniline (DEAN) on emission properties of a coumarin derivative 6-methyl-3azidoacetyl coumarin (6M3AAC) in acetonitrile was studied by means of steady state fluorescence spectroscopy. The quenching of fluorescence intensity was observed in the presence of amines. The quenching process was characterized b...
متن کاملPreparation of sterically congested 1,3,4-oxadiazole derivatives from N-isocyaniminotriphenylphosphorane, aromatic acids, cyclopentanone and primary amines
Reactions of N-isocyaniminotriphenylphosphorane with cyclopentanone have been studied in the presence of aromatic carboxylic acids and primary amines, proceeds smoothly at room temperature under neutral conditions to afford sterically congested 1,3,4-oxadiazole derivatives by an intramolecular Aza-Wittig cyclization in CH2Cl2 in excellent yields. The structures of the products were deduced from...
متن کاملOn the Fluorescence Quenching of Polycyclic Aromatic Hydrocarbons by Nitromethane
Fluorescence quenching of 22 polycyclic aromatic hydrocarbons by nitromethane in toluene and acetonitrile solutions has been studied. Contrary to Sawicki's observations that the fluorescence of hydrocarbons with the fluoranthene skeleton is not quenched that of 11J2and 3.4-benzofluoranthene and fluoranthene itself is quenched. These compounds have a high energy of the fluorescence transition. T...
متن کاملQuantum-chemical studies on mutagenicity of aromatic and heteroaromatic amines.
Arylamines are well-known as widespread industrial and environmental mutagens and carcinogens. Their bioactivity stems from enzymatic metabolic activation to reactive and highly electrophilic intermediates. In this work, computational investigations related to the biological activity of these compounds have been reviewed, especially focusing on studies reporting results from quantum-mechanical ...
