Two kinds of “butterfly‐shaped” host compounds, 2,5‐bis(triphenylmethyl)hydroquinone ( 1 ) and 2,5‐bis(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: 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‐pyrrolidone (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.
