Simple tris(2-aminoethyl)amine (TREN) based tripodal urea receptors are investigated for the encapsulation of divalent oxalate (C2O4(2-)) in a semi-aqueous medium. A single crystal X-ray diffraction study shows that the receptor with 3-cyanophenyl functionality captures a staggered conformer whereas the 3-fluorophenyl functionalized receptor encapsulates a less stable planar conformer.
研究了基于简单的三(2-氨基乙基)胺(TREN)的三足尿素受体,以在半水介质中包封二价草酸盐(C2O4(2-))。单晶 X 射线衍射研究表明,具有 3-氰基苯基官能团的受体捕获了交错构象,而 3-氟苯基官能化的受体则包封了不太稳定的平面构象。
