ring compounds exhibited mesomorphism. Smectic C, smectic A, and nematic phases were observed by optical microscopy and DSC analysis. The yield of these reactions varied from moderate to excellent (47–93%). The structure of the rigid core was investigated by single crystal X-ray diffraction, which confirmed the regioselectivity of the [3+2] dipolar cycloaddition reaction.
