摘要:
Three polyesters have been prepared which incorporate the cyclooctyl unit in the main chain. The number of phenyl rings in the repeat unit was varied from one to three and in each case the polymer exhibited a liquid-crystalline phase. It has been shown that the cyclooctyl ring may act both as a semi-flexible spacer as well as an integral part of the mesogenic unit. This dual role is of considerable interest and has not been reported previously.
