Abstract
- A novel selective and sensitive colorimetric receptor 1 (1, 10-phenanthroline-2, 9-dialdehyde bis-(-p-nitrophenylureasemicarbo-hydrazone)) based on urea showing distinctive color fading phenomenon towards H<subscript>2</subscript>PO<subscript>4</subscript><superscript>−</superscript> ion was reported. Fancifully, the recognition process of receptor 1 to H<subscript>2</subscript>PO<subscript>4</subscript><superscript>−</superscript> was not interfered by the existence of others anions. We have probed the binding mechanism of 1-H<subscript>2</subscript>PO<subscript>4</subscript><superscript>−</superscript> that H<subscript>2</subscript>PO<subscript>4</subscript><superscript>−</superscript> ion induced competitive hydrogen binding process via intramolecular hydrogen-bond by UV-vis, fluorescence, <superscript>1</superscript>H NMR titrations and ESI-MS experiments.
