title: H(+)-Assisted fluorescent differentiation of Cu(+) and Cu(2+): effect of Al(3+)-induced acidity on chemical sensing and generation of two novel and independent logic gating pathways.
abstract: A novel Schiff base probe exhibited strong 'turn-ON' fluorescence for Cu(2+) at 345 nm, Al(3+) at 445 nm, and Cu(+) at 360 nm in the presence of Al(3+) in organic solvent (acetonitrile), which allowed for construction of molecular logic gates 'INH' and '1:2 DEMULTIPLEXING.' H(+) generated from Al(3+) contributed greatly to Cu(+) chemosensing based on a redox non-innocence mechanism.
