A novel tris(4-carboxyphenyl)cyclotriguaiacylene 2 was synthesized by hydrolysis of a novel tris[(4-(methoxycarbonyl)phenyl]cyclotriguaiacylene. The structure was determined by 1H NMR, 13C NMR and mass spectroscopic techniques. The crystal structure of 2 was shown by X-ray crystallography to have a face-to-face structure of a pair of molecules of 2. The structure was constructed from 3D hydrogen-bonded...
