Tripodal ligand incorporating dual fluorescent ionophore: a coordinative control of photoinduced electron transfer.


p-(N,N-Dimethylamino)benzenesulfonamide (DMABSA), a dual fluorescent fluorophore, has been derivatized into two new fluoroionophores for transition metal cations. The electron-acceptor sulfonamide group has been N-substituted by a 2-pyridylmethylene group to lead to a bidentate ligand which forms a 2:1 complex with Cu(II). The crystal structure of the… (More)
