17 new mono-substituted ferrocene containing ester and Schiff base typescomplexes which contain 3 of 4 benzene rings, an alkoxyl group of different length and a rigid core of different length have been synthesized and characterized, and their mesogenic behaviors have been studied through DSC and optical microscope. The lengh 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, which depend on the length of the rigid core. When the rigid core is long enough,the complex can have liquid crystal properties even if terminal chain is H. This is the first organometallic liquid crystal compound without soft terminal chain.
