An azo dye-coupled tripodal chromogenic sensor for cyanide

Lee, D.Y.; Singh, N.; Satyender, A.; Jang, D.O. (2016-05-12)

A tripodal receptor bearing phenol as a hydrogen bond donor site and azo dye as the signaling subunit was synthesized. The receptor had a high binding affinity for CN− as signaled by the change in the color of a solution ...
A benzimidazole-based single molecular multianalyte fluorescent probe for the simultaneous analysis of Cu2+ and Fe3+

Lee, D.Y.; Singh, N.; Jang, D.O. (2017-02-27)

We synthesized a novel receptor with benzimidazole moieties in a tripodal framework. The receptor displays rarely observed metal specific fluorescence enhancement at two different wavelengths. The receptor was investigated ...
Fine tuning of a solvatochromic fluorophore for selective determination of Fe3+: a new type of benzimidazole-based anthracene-coupled receptor

Lee, D.Y.; Singh, N.; Jang, D.O. (2016-05-13)

We synthesized a novel benzimidazole-based, anthracene-coupled fluorescent receptor capable of recognizing and estimating the concentrations of Fe3+ in semi-aqueous solution by ratiometric estimation. Our sensor can be ...
Ratiometric and simultaneous estimation of Fe3+ and Cu2+ ions: 1,3,5-substituted triethylbenzene derivatives coupled with benzimidazole

Lee, D.Y.; Singh, N.; Jang, D.O. (2016-05-13)

We synthesized a novel 1,3,5-substituted triethylbenzene derivative with a benzimidazole moiety as a binding and signalling subunit. The triethylbenzene platform was judiciously incorporated into the receptor design such ...
Ratiometric fluorescent determination of Zn(II): a new class of tripodal receptor using mixed imine and amide linkages

Lee, D.Y.; Singh, N.; Kim, M.J.; Jang, D.O. (2016-05-12)

We synthesized a novel receptor with a unique combination of sp2 nitrogen (eCH]Ne) and carbonyl groups from amide linkages. These two moieties are judiciously incorporated into the receptor design such that these sites ...
Single sensor for multiple analytes: chromogenic detection of I− and fluorescent detection of Fe3+

Jung, H.J.; Lee, D.Y.; Jang, D.O. (2016-05-12)

A novel receptor, designed with a combination of oxygen and nitrogen-binding sites for metal ions and hydrogen bond donor sites for anion binding, was synthesized. The receptor has been explored for the selective detection ...
