Abstract
Imidazo[1,5-a]pyridinium salts( L),was synthesized with aniline by a facile three-component coupling. The structure was confirmed by1 H NMR and13 C NMR,IR,X-ray crystal diffraction analysis. The recongnition properties of L with p-phthalic acid( A1),4,4'-dipyridyl( A2),pyridine( A3),propanedioic acid( A4),1,8-diaminonaphthalene( A5) were investigated in acetonitrile by fluorescence. The results showed that L exhibited selectively recognition properties for p-phthalic acid.
