Abstract

The fluorescent natural products, quinine, quinidine, cinchonine and cinchonidine are demonstrated as H⁺-enabled, halide-disabled (Cl^-, Br^- or I^-) INHIBIT and INHIBIT-OR combinatorial logic gates in water. More fluorescent natural products with intrinsic logic properties await to be discovered.
