Studies concentrating on hydrogen bonding interactions between 2-amino-4-methylpyrimidine (AMPY) with selected dicarboxylic acids have been investigated in the solid state. Two pyrimidinium-dicarboxylate organic salts with stoichiometry 1:1 [AMPY: maleic acid] and 2:1 [AMPY:d(+)-malic acid] have been prepared and characterized by X-ray crystallographic analysis. Maleic and d(+)-malic acids were found...
1,10-phenanthroline-based fluorescent chemosensor has been designed and synthesized for the recognition of urea and 1,3-dimethyl urea in CH 3 CN. Interactions of this compound with urea and 1,3-dimethyl urea are studied with UV–visible and fluorescence spectroscopic methods. 1,10-phenanthroline was found to be capable of distinguishing urea from 1,3-dimethyl urea. The formation of a highly...
