Abstract
In the present work, the photopysical properties of the series of 6-amino-substituted 1,3-diphenyl-1H-pyrazolo[3,4-b]quinoline (carbazol-, N,N-diphenyl-, N,N-phenyl-1-naphthyl-, N,N-dimethyl-) and with a special attention to the solvatochromism, acidochromism, solid state fluorescence and electron transfer process has been presented. The Lippert-Mataga plot for the compounds under study is clearly non-linear. Additionally, the Kamlet
