Optical properties of some 4-aryl-1H-pyrazolo [3, 4-b] quinolines

Abstract

Series of 6-substituted 4-(4'-tolyl)-3-methyl-l-phenyl-1H-pyrazolo[3,4-b]quinolines (1) and 4-(4'-chlorophenyl)- 3-methyl-1-phenyl-1H-pyrazolo[3,4-b]quinolines (2) were synthesized and their solution absorption and emission spectra in 10 solvents were recorded. Positions and intensity of the emission and longest wavelength absorption band as well as the quantum yield of emission and its lifetime were analysed in terms of the corresponding identity criteria involving a given parameter i from series (1) against the same parameters from the series (2). Mostly only tendencies to the linearity were observed in terms of the correlation coefficient.
