The synthesis and metal binding properties of cation-sensitive fluorescent indicators intended for biological applications are described. The increase of the crownetherring size enhances the affinity for larger cations, but weakens the fluorescent response and selectivity. A compound having a 15-crown-5 chelator directly attached to a 2,7-difluoroxanthenone fluorophore loads into live cells and responds
