“…If the absorption/FL value exceeds the set threshold, it will be considered binary 1, and if it falls below, it will be considered binary 0. Following these orthodox molecular logic gate designing approach, ,,,− we have proposed herein a range of optically adaptive molecular NOR, AND, IMPLICATION, INHIBIT, TRANSFER, COMPLEMENT, etc. The most exciting element of the current study is how a single photochemical system can be simply modified to achieve incredibly precise binary logic features (such as NOR, INHIBIT, TRANSFER, etc.)…”

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.

“…Understanding this relationship is crucial for optimizing dye-micelle systems for various applications, including drug delivery, sensing, or catalysis, where controlled aggregation and precise dye localization are essential factors. [18,19] Thus, in the present study, we compared the metal ion sensing properties of two pyridine-end oligo p-phenylenevinylene compounds with different alkyl substituents in a micelle medium (Figure 1a). It was observed that the location of the probe molecules in the micelle depends on the length of the alkyl chains, influencing their self-assembly behaviour and optical properties.…”

In this work, we conducted a comparative analysis of the metal ion sensing capabilities of two pyridine‐end oligo p‐phenylenevinylene compounds featuring different alkyl substituents (‐C4H9 and ‐C16H33) within a micelle medium. Our findings revealed a correlation between the positioning of the probe molecules within the micelle and the length of the alkyl chains, impacting their self‐assembly tendencies and optical characteristics. The compound with shorter alkyl chains demonstrated a superior affinity towards Hg2+ ions, whereas exposure to the compound with longer alkyl substituent resulted in a color‐changing response with both Cu2+and Hg2+ ions. Intriguingly, the sensitivity towards Hg2+ ions heightened with increasing alkyl chain length. This trend persisted in non‐polar solvents like THF. The capacity to modulate sensing efficacy solely by adjusting the length of the alkyl chains represents a relatively uncommon occurrence in the existing literature. This discovery suggests promising prospects for engineering sensory devices equipped with adaptable sensitivity.
