Abstract

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

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