Eight new 3,6-disubstituted pyridazines, which contain cholesteryl, two benzene rings, an Schiff base, an ester function and an alkoxyl group of different length, have been synthesized and characterized. Their mesomorphism has been studied through differential scanning calorimetry. The length of the terminal chain can affect the transition and clearing point temperatures of the compounds, but has little influence on the temperature range of mesomorphous phases, which could depend on the length of the rigid core.

Key words: cholestryl, cross-coupling reaction, mesomorphism, pyridazine derivative
