Excited state kinetics in crystalline solids: Self-quenching in nanocrystals of 4,4′-disubstituted benzophenone triplets occurs by a reductive quenching mechanism
(American Chemical Society, 2011-11)
We report an efficient triplet state self-quenching mechanism in crystals of eight benzophenones, which included the parent structure (1), six 4,4′-disubstituted compounds with NH 2 (2), NMe 2 (3), OH (4), OMe (5), COOH ...
Determination of the pKa of hydroxy-benzophenones in ethanol-water mixtures. Solvent effects
(Elsevier Science, 2003-05-30)
Benzophenones are compounds of great importance due to their biological and physicochemical properties. The purpose of the present work was to determine by a UV-Visible spectroscopic method, the pKa of 4(OH)benzophenone, ...
Experimental and DFT study on the indiummediated synthesis of benzophenones via arylstannanes
(Royal Society of Chemistry, 2014-09)
Experimental results of the solvent-free, indium-promoted reaction of aroyl chlorides with arylstannanes showed a narrow scope; its efficiency depends both on the extent of methylation in the latter and on the nature, ...
Synthesis of 1,2,3-triazole benzophenone derivatives and evaluation of in vitro sun protection, antioxidant properties, and antiproliferative activity on HT-144 melanoma cells

PHOTOINTERACTION OF BENZOPHENONE TRIPLET WITH LYSOZYME
(1989)
Abstract The quenching of the benzophenone triplet by lysozyme and its constituent amino acids in aqueous solutions have been studied. Native lysozyme quenches the benzophenone triplet with a high rate constant, 4 × ...
