文摘

4,4'-(9-Fluorenylidene)diphenol (FDP) and/or 4,4'-cyclohexylidenebisphenol (CBP) is crystallized withbipyridine bases 4,4'-bipyridyl (bipy), 1,2-bis(4-pyridyl)ethane (bipy-eta), 1,2-di(4-pyridyl)ethylene (dipy-ete), and4,4'-dipyridyl N,N'-dioxide (dipy-dox) to afford molecular complexes (FDP)·(bipy) 1, (FDP)·(bipy-eta)_0.5 2, (FDP)₂·(dipy-ete) 3, (FDP)·(dipy-dox) 4, and (CBP)·(bipy) 5. The crystal structures of 1-5 have been determined by single-crystal X-ray diffraction. All these molecular complexes exhibit polymeric supramolecular structures via O-H···Nor O-H···O hydrogen-bonding. 1 forms double helices. 2 forms an infinite honeycomblike supramolecular structure.3 forms a brick supramolecular structure. 4 forms an X-shaped supramolecular structure. 5 forms a single strandinfinite helix. Thus, by changing the guest molecule, we can obtain different supramolecular hydrogen-bondedpolymers through interactions of host-guest systems.
