✦ Synopsis

The deactivation mechanism of the excited charge-transfer complex in non-polar and pohr solvents has been discussed on the basis of measured quantum yields and decay times of fluorescence of charge-transfer complexes of pyromellitic dianhydride with some methylbenzenes.

It has been pointed out that great changes of electronic structure in the excited state, caused by strong excited complex-solvent interaction, are responsible for the very low fluorescence quantum yield observed in polar solvents.

Al&met-The formation of charge-transfer complexes can be followed by conductimetric titration. Either a donor solution is titrated with a solution of an acceptor, or vice versa, both using the same solvent. A theory is presented requiring the conductivity to pass through a maximum when donor and acc
