A new fluorescent sensor 5 having fused imidazopyridine scaffold has been synthesized via cascade cyclization. It exhibits highly sensitive and selective detection of Fe3+ (‘turn-on’) and Hg2+ (‘turn-off’) in vitro and in HeLa cells.
Two organic–inorganic hybrid nanomaterials were prepared and were used as chemosensors for the selective detection of nitroaromatic explosives in aqueous media.
