Simple tris(2-aminoethyl)amine (TREN) based tripodal urea receptors are investigated for the encapsulation of divalent oxalate (C2O42−) 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.
研究了在半水介质中封装二价草酸盐(C2O42-)的基于简单三(2-氨基乙基)胺(TREN)的三联脲受体。单晶 X 射线衍射研究表明,具有 3-氰基苯基官能团的受体能捕获交错构象,而具有 3-氟苯基官能团的受体则能封装稳定性较差的平面构象。
