Five BODIPY analogs modified at the meso-position were synthesized through a Mannich-type reaction. Among these derivatives, aza-12-crown-4 analog 3c was found to show Cu2+-specific behaviour in UV/vis and fluorescent spectra, leading to blue shifts

A simple Schiff base type fluorescent receptor 1 was prepared and evaluated for its fluorescence response to heavy metal ions. Receptor 1 exhibits an ‘off–on-type’ mode with high selectivity in the presence of Zn 2+ ion. The selectivity of 1 fo

A simple Schiff-base receptor 2 was prepared. It exhibits an “off-on-type” mode with high sensitivity in the presence of Al3+. The receptor 2 exhibited a high association constant with submicromolar detection for Al3+ in EtOH–H2O (95:5 v/v) sol

Sugar-aza-crown ether-based cavitand 1 can act as a selective turn-on fluorescence sensor for hydrogen sulfate ion in methanol among a series of tested anions. Spectroscopic studies, particularly NMR spectroscopy, revealed that the C–H hydrogen bon
