A nove approach to mesomorphism is reported in which discotic pyrazole derivatives are formed by dimerization of half-disk-shaped promesogenic pyrazoles throught BH2 bridges. The figure show the texture of the Dhd mesophase exhibited by one of the resulting pyrazoboles. How the mesomorphism is affected by the number and position of peripheral chains is alos described.
