| Research Abstract |
We synthesized helical aliphatic and aromatic conjugated polymer films such as helical polyacetylene (PA) and poly(3,4-ethylenedioxythiophene) (PEDOT) films in a chiral nematic liquid crystal (N*-LC) as an asymmetric reaction field. The helical conjugated polymer films were then carbonized and subsequently graphitized, yielding helical carbon and graphite films, respectively. The screw direction, degree of twist, and macroscopic alignment of the helical graphite film were well controlled by changing the sense and pitch of the helix, and the orientation of the asymmetric LC field. Furthermore, macroscopically aligned graphite whiskers were prepared from self-assembled aromatic conjugated polymers of poly(meta-phenylene) derivatives as carbonization and graphitization precursors.
