A simple and reliable colorimetric probe N,N'-Bis-(4-diethylamino-2-hydroxybenzylidene)-1,10-phenanthroline-2,9-carbohydrazide (L) has been synthesised by reacting 4-(diethylamino) salicylaldehyde with 1,10-phenanthroline-2,9-dicarbohydrazide. Sensing ability of L was studied by interacting with various f-block metal ions...
