Abstrakt:	The presence of active methylene group in the molecules of cyclopenta[ c]quinolinium quarternary salts permitted to obtain products of their reaction with p-dimethylaminobenzaldehyde. Structures of the reaction products were established from 1H and 13C NMR spectral data using the correlation spectra. The effect of substituents at nitrogen on the visible absorption spectra was studied. The investigation of formation of the frontier orbitals in the reaction products by quantum chemical calculations revealed the reason of the coloration of the dyes synthesized. [ABSTRACT FROM AUTHOR]
