Abstract
A new substituent triphenodioxazine compound containing the 3,10-di(N-benzoyl-N-phenyl) amino has been synthesized. The benzoyl groups were introduced into the molecule during the cyclization of the dianilide derived from 4-amino-diphenylamine in the presence of benzoyl chloride as ring closure agent. The absorption and fluorescence spectra of the dye were measured in five solvents and it was found that the fluorescence quantum yields, Stokes shifts and molar extinction coefficients varied linearly with E T of the solvents. When using p-toluene sulphonyl chloride as ring closure agent, p-toluene sulphonyl groups were also introduced.
