【 摘 要 】

Tris(2-aminoethyl)amine (TREN) based pentafluorophenyl urea and 4-cyanophenyl thiourea receptors have shown encapsulation of oxalate (C2O$^{2−}_{4}$) in semi-aqueous environment. A single crystal X-ray study shows trapping of planar conformer of C2O$^{2−}_{4}$ in both the cases. Further solution state binding of C2O$^{2−}_{4}$ is probed by 1H-NMR titration study in semi-aqueous solvent.
