✦ Synopsis

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 1 H NMR spectroscopy, and the results were as follows:

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.
