- •
Two new two photon chemosensors CCP and COP were synthesized and fully characterized.
- •
They show strong fluorescence quenching and good ratiometric responses.
- •
The two-photon fluorescence intensity could be effectively enhanced on adding EDTA.
- •
The internalization (CCP → Fe3+, COP → Cu2+) with cells and shows the “light switch” property.
