The synthesis of N-methylphthalimides substituted with the donor groups pyrazole, triazole, benzotriazole, and naphthotriazole in position 4 is described (17, 18, 14, 12).The substituent constants of these groups are obtained by alkaline hydrolysis of the corresponding phthalimide dyes.Their solvatochromism in absorption and fluorescence gives information about charge distribution in ground- and excited state.
