SYNTHESES AND CHARACTERISATION OF MOLECULAR TWEESORS FOR THE RECOGNITION OF GUEST SUBSTRATES
Journal Title: ASIAN JOURNAL OF NATURAL & APPLIED SCIENCES - Year 2012, Vol 1, Issue 2
Abstract
Two novel amido anion receptors were synthesized from building block 3,3’ methylene diamine and was characterized via the techniques of 1H NMR, 13 C NMR, DEPT- 135 spectroscopy, 1H-1H COSY, HMQC and HMBC. Preliminary anion binding studies via 1 HNMR spectroscopy revealed complexation with phosphate anions in the highly competitive solvent, d6-DMSO. This paper focuses on the syntheses, characterization and preliminary anion binding studies of molecular clef type receptors (4) and (5) incorporating the amide, -HNCOunits. These receptors are built on the molecular scaffold of 3,3’ methylene diamine and present convergent binding sites to anionic substrates.
