本文报道了O-烷氧基戊酸（5-C12和4-C12）与4，4 ′-联吡啶（bipy）分子配合物在晶格中的自组装。配合物5-C12 ISA·bipy和4-C12 ISA·bipy通过氢键、烷基链间的相互作用、π-π和C-H-π相互作用形成三维超分子结构。前者形成独特的三重螺旋，其进一步组装成通过π-π堆积相互作用稳定的2D网络。后者形成氢键超分子片。
Self-assembly of the molecular complexes of O-alkoxy isophthalic acid (5-C12 and 4-C12) with 4,4′-bipyridine (bipy) in the crystal lattice is described. Complexes 5-C12ISA·bipy and 4-C12ISA·bipy exhibit 3-D supramolecular structures through and interplay of H-bonding, alkyl chain interdigitation, π⋯π and C–H⋯π interactions. The former forms a unique triple helix which further assembles into a 2D network stabilized via π⋯π stacking interactions. The latter forms hydrogen bonded supramolecular sheets.
