“…The red-shift phenomenon suggested that the probe was susceptible to intramolecular charge transfer when bound to Cu 2+ , and the appearance of absorption bands at 500 nm and 520 nm may be attributed to intramolecular charge transfer interactions. 49–51 As the concentration of Cu 2+ increases, the fluorescence intensity at 500 nm slowly decreased and CCU was dynamically responsive to the concentrations of Cu 2+ in the range of 10–90 μM (Fig. 1B and C).…”

“…Especially, the pyridine-end oligo- p -phenylenevinylene derivatives are often used for detection of metal ions and local pH, which make them valuable tools for monitoring and assessing environmental quality . Due to harmful effects that heavy metal pollutants like Cu 2+ and Hg 2+ have on the environment and human health when they are present in excess, color change in reaction to these contaminants is extremely significant. − …”

The paper describes an improved method for building flexible interswitchable logic gates such as rare-type molecular ternary INHIBIT and combinational logic circuits using a specially designed pyridine-end oligo-p-phenylenevinylene compound featuring alkyl substituents (−C 16 H 33 ) in a THF medium. The probe molecule showed distinct opto-chemical signals upon interaction with Cu(II) and Hg(II) in THF medium. It is interesting to note that the presence of certain anions (S 2− , I − , and CN − ) could specifically mask the interaction of either of these metal ions or both. The most exciting thing is that we used a completely new gate design technique to construct a rare-type ternary INHIBIT logic gate using Cu(II), Hg(II), and CN − ions as three chemical inputs. With the identical set of chemical inputs, two more ternary combinational logic circuits were created out of these casespecific, independent reversible and irreversible spectroscopic studies. Finally, we were able to design adaptive molecular logic systems composed of several logic gates, including NOR, AND, IMPLICATION, INHIBIT, TRANSFER, and COMPLEMENT, that in this specific situation change the sort of logic sense by effortless optical toggling.
