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.
A highly sensitive and selective fluorescent sensor based on aggregation-induced emission (AIE) for Cu2+ in THF/H2O 1 : 9.
Designing exceptional probes to detect minute quantities of chromium(vi) is of huge importance for the safety and health of the human race.
