Two kinds of "butterfly-shaped" host compounds, 2,5-bis(triphenylmethyl)hydroquinone (1) and 2,5bis(diphenylmethyl)hydroquinone (2) were designed and synthesized. 1 and 2 can form inclusion complexes with various small organic molecules. These inclusion complexes were determined by H-1 NMR spectroscopy, and the results were as follows: 1.DMF (1 : 2), 1.DMSO (1 : 2), 1.pyridine (1 : 2), 1.cyclopentanone (2 : 3); 2.DMF (1 : 2), 2.THF (1 : 1), 2.benzaldehyde (1 : 2), 2.2,5-hexanedione (1 : 1), 2.N-methyl-2-pyffolidone (1 : 3). The complex structure of 2 with benzaldehyde was determined by single crystal X-ray diffraction analysis and the crystal structure is stabilized by intermolecular hydrogen bonds.
