摘要: Abstract The fluorescence of quenching carbazoles and indoles by ethylenetrithiocarbonate has been studied. Both steady-state transient experiments were carried out in order to determine rate constants the case carbazoles. results obtained support charge-transfer mechanism. Ground-state complex formation is assumed explain higher for indole its derivatives, which appear as positive curvatures Stem-Volmer plots.
