Molecular trafficking based on latch circuit.
A new fluorescent chemosensor 3 based on calix[4]arene of partial cone conformation possessing dansyl moieties has been synthesized. The chemosensor demonstrates selective optical recognition of Hg(2+) ions in mixed aqueous media and mimics the operation of a traffic signal based on the R-S Latch Logic circuit with pH, Hg(2+) and Cl(-)/Br(-)/I(-) as chemical inputs.
