dc.description.abstract | A novel fluorescent molecular logic gate with a ‘fluorophore–spacer1–receptor1–spacer2–receptor2’ format is demonstrated in 1 : 1 (v/v) methanol/water. The molecule consists of an anthracene fluorophore, and tertiary alkyl amine and N-(2-methoxyphenyl)aza-15-crown-5 ether receptors. In the presence of threshold concentrations of H+ and Na+, the molecule switches ‘on’ as an AND logic gate with a fluorescence quantum yield of 0.21 with proton and sodium binding constants of log βH+ = 9.0 and log βNa+ = 3.2, respectively. At higher proton levels, protonation also occurs at the anilinic nitrogen atom ether with a log βH+ = 4.2, which allows for Na+, H+-enabled OR (OR + AND circuit) and H+-driven ternary logic functions. The reported molecule is compared and contrasted to classic anthracene-based Na+ and H+ logic gates. We propose that such logic-based molecules could be useful tools for probing the vicinity of Na+, H+ antiporters in biological systems. | en_GB |
