摘要
Eight new 3alkoxy6(4methylphenyl)pyridazines which contain a benzene ring,an alkoxyl group of different length were synthesized through the crosscoupling reaction of 3halo6alkoxypyridazines with 4methylphenylborate in the presence of palladium catalyst.Their mesogenic behaviors were studied through DSC and optical microscope.The length of the terminal chain can affect the transition and clearing point temperatures of the complexes,but has little influence on the temperature range of mesophases.
