| Abstract: | Eight new 3,6-disubstituted pyridazines which contain ferrocene, three 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 calorimetry (DSC). 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 mesomorphous phases, which depend on the length of the rigid core. |

| Keywords: | ferrocene pyridazine derivative cross-coupling reaction mesomorphism |
