Cruz C, Calisto V, Delgado R, Felix V: Design of protonated polyazamacrocycles based on phenanthroline motifs for selective uptake of aromatic carboxylate anions and herbicides. Chemistry. 2009;15(13):3277-89.
Analysis shows that molecular recognition is governed by pi-pi stacking interactions and multiple N--HO==C hydrogen bonds.Three novel large polyazamacrocycles containing two 1,10-phenanthroline (phen) units connected by two polyamine spacers of different length, [32] phen (2) N (4), [30] phen (2) N (6) and Me (2)[34] phen (2) N (6), have been synthesised and their protonated forms used as receptors for binding studies with several aromatic carboxylate anions (benzoate (bzc (-)), 1-naphthalate (naphc (-)), 9-anthracenate (anthc (-)), pyrene-1-carboxylate (pyrc (-)), phthalate, (ph (2-)), isophthalate (iph (2-)), terephthalate (tph (2-)), 2,5-dihydroxy-1,4-benzenediacetate (dihyac (2-)) and, 1,3,5-benzenetricarboxylate (btc (3-))) and three herbicides (4-amino-3,5,6-trichloropyridine-2-carboxylate (ATCP (-)), dichlorophenoxyacetate (2,4-D (-)) and glyphosate (PMG (2-))) in water solution. |
