Six novel ferrocene-containing compounds with structure of Fe-C 6H 4-O 2C-C 6H 3(Br)-OC 10 H 21 ,compound 7,and Fe-C 6H 4-N=CH-C 6H 4-O 2C-C 6H 3(Br)-OC nH 2n+1 (Fe:ferrocenyl;n=2,4,6,8,10,compound 8,9,10,11,12)(series Ⅰ)were prepared.Their mesogenic behaviors were studied with DSC and polarized microscopic.The result showsed that compoud 7 did not possess liquid crystalline properties,while series Ⅰ compounds had narrow liquid crystal temperature range.
