摘要

Six new supramolecular structures have been prepared by bis(2-hydroxy-5-chlorophenyl) sulfide (HCS) and/or spirobicromane (SBC) with bipyridine bases 4,4'-bipyridyl (bipy), 1,2-di(4-pyridyl)ethylene (dipy-ete), 1,2-bis(4-pyridyl)ethane (bipy-eta), and 4,4'-dipyridyl N,N'-dioxide (dipy-dox). These molecular complexes are (HCS)(bipy) 1, (HCS)(.)(dipy-ete) 2, (HCS)(.)(bipy-eta) 3, (HCS)-(dipy-dox)4, (SBC)-(dipy-ete) 5, and (SBC)-(dipy-dox)(H2O)-H-. 6, respectively. The crystal structures of 1-6 have been determined by single crystal X-ray diffraction. All of these molecular complexes exhibit supramolecular structures via O-(HN)-N-... or O-(HO)-O-... hydrogen bondings. Both 1 and 2 form interestingly [2 + 2] macrocyclic structures, whose sizes are ca. 12.495(6) angstrom x 5.087(6) angstrom and 14.774(6) angstrom x 5.300(6) angstrom, respectively. Compounds 3 and 5 form one-dimensional zigzag chain structures. Compounds 4 and 6 form two-dimensional double helices. These results demonstrate that by changing the guest molecule, we can obtain different hydrogen-bonded supramolecular structures through different interactions.
