A simple tailor-made amidic functionality based on 1,10-phenanthroline unit (1) gave differential absorption changes with only metal ions viz. Cd2+, Zn2+, and Cu2+ ions. In CH3CN solution of 1, addition of Cd2+ and Zn2+ ions resulted in bathochromic shift of similar to 65 nm, whereas Cu2+ ions resulted in hyperchromic effect with only 15 nm bathochromic shift. These differential changes observed with Cd2+ and Cu2+ ions addition enabled chemosensor 1 to construct 'IMLICATION' and 'TRANSFER' logic gates.
