A new class of tripodal N-ligands have been prepared under mild conditions by reaction of N-hydroxymethyl-3,5-dimethylpyrazole with 2-furylmethylamine; 2-pyridylmethylamine; 4-nitrobenzaldehyde hydrazone and (E)-1-((anthracen-9-yl)methylene)hydrazine in a double equimolar ratio (2:1). The tripodal ligands were characterized by IR, 1H-, and 13C-NMR, microanalysis, and mass spectrometry. The fluorescence properties of the ligands were analyzed.
