Özet

The spectral-fluorescent properties of substituted 2- and 4-(N-arylimino)quinolines have been investigated in solvents of different polarity and proton donating ability, and in immobilized phases of PVC films and sol-gel matrix. The effect of the solvent on spectral characteristics has been estimated. It has been shown that, despite the possibility of quenching process linked with intramolecular motions with great amplitude of the non-fixed azomethine fragment, the low fluorescence quantum yield of the studied compounds in polar solvents and in immobilized phases is caused mainly by the quenching process which is not linked directly with significant changes in molecular geometry.
