Hydrosilylation of poly(ferrocenylmethylhydrosilane) [Fe(η-C 5 H 4 ) 2 SiMeH] n with 1-hexene and ethyl acrylate was achieved using Karstedt's catalyst with degrees of functionalization of ca 80%. Using a similar strategy, 4-pentoxy-4 -hydroxyhexanoxyazobenzene or 4-pentoxy-4 -hydroxyundecyloxyazo-benzene acrylate side chains were successfully attached to the poly(metallocene) main chain. The resulting functionalized poly(ferrocenylsilanes) represent the first examples of calamitic thermotropic side chain liquid crystal polymers with ferrocene groups in the backbone.
