Rate constants of quenching of the fluorescence of pterins by the iodide anion in aqueous solution
(Elsevier Science, 2012-07)
The fluorescence of various pterins (6-methylpterin, 6-hydroxymethylpterin, 6-formylpterin, and 6-carboxypterin) was quenched using iodide in neutral, aerated neutral phosphate buffer. Stern-Volmer plots and the fluorescence ...
Propagation chains in photocatalyzed radical nucleophilic substitutions of thiolates with perfluoroalkyl groups
(Elsevier Science, 2020-10)
Quantum yields and radical chain lengths have been investigated in photocatalyzed radical nucleophilic perfluorobutyl group substitution reactions of 2-mercaptothiolate anion under three different photocatalytic systemsoperating ...
Excited states quenching of phenosafranine dye by electron donors
(Elsevier Science Sa, 2005-03)
The quenching of the excited singlet and triplet states of phenosafranine by aromatic amines, methoxybenzenes and triethanolamine was investigated in acetonitrile and methanol. The rate constants for the aromatic quenchers ...
Quenching of the Singlet and Triplet Excited States of Pterin by Amino Acids
(Wiley Blackwell Publishing, Inc, 2019-01)
Unconjugated oxidized pterins accumulate in the skin of patients suffering from vitiligo and, under UVA irradiation, photosensitize the oxidation of amino acids. In this work, we study the interaction of the singlet and ...

Interactions between imazethapyr and bovine serum albumin: Spectrofluorimetric study
(Elsevier Science, 2012-10)
The interaction between imazethapyr (IMA) and bovine serum albumin (BSA) was investigated by fluorescence spectroscopy. The Stern-Volmer quenching constant (K SV) at three temperatures was evaluated in order to determine ...
Concentration quenching of the green photoluminescence from terbium ions embedded in AlN and SiC matrices
(Elsevier BVAmsterdam, 2013-05)
The green photoluminescence emission from terbium rare earth ions embedded in the wide band gap matrices wurtzite AlN and amorphous 'SI'C shows the same functional rapid decay with increasing concentration (concentration ...
