Crystal growth of 1-methyl-4-{2-[4-(dimethylamino)phenyl]-ethenyl} pyridinium p-toluenesulfonate (DAST) and 1-methyl-4-{2-[4-(dimethylamino)phenyl] etheny} pyridinium p-chloroben-zenesulfonate (DASC) was carried out by using the slope nucleation method with solution cooling. DASC crystals were found to be more resistant to water in comparison with DAST.
