|Abstract: ||After Ringsdorf and coworkers proposed that a flexible spacer should be inserted between the polymeric main chain and the mesogenic side group in order to decouple the motion of the main chain from the side group, systematic synthesis, characterizations and applications of side chain liquid crystalline polymers became popular. Attachment of mesogen pendant to the conjugated polyacetylene backbone is of interest because the resulting polymers may possess unique electrical and liquid crystalline properties.
Recently, we have synthesized two mesogen-containing polyalkynes (PA3OE11 and PA3EE11) with different attachment bridges according to Schemes 1 and 2. In this paper, we report the synthesis and mesomorphic properties of the monomers and polymers with different bridge groups.|
