A ratiometric fluorescent molecular probe with enhanced two-photon response upon Zn 2+ binding for in vitro and in vivo bioimaging
A bipyridine centered donor–acceptor–donor (D–π–A–π–D) type ratiometric fluorescent molecular probe exhibited an unprecedented enhancement in the two-photon absorption (2PA) cross section upon Zn2+ binding. Moreover, owing to the excited state charge-transfer of the fluorophore π-backbone, a signifi...
