Abstract
A series of unsubstituted and 1,4-disubstituted gallic catecholates 1, 6 and 7 as possible candidates for wedge-shaped mesogens were prepared starting from the respective benzene derivatives 2a-c and gallic esters 5a-h. The mesomorphic properties were investigated by DSC. However, only the 4,5-dinitro derivatives 1d,f-h with C8H17 and C10H21 to C12H25 alkyl side chains displayed mesophases, as evaluated by fluidity and optical anisotropy.
