We have synthesized the ester derivatives of hydroxypropylcellulose by a reaction with alkanoic acids with a carbon number of 2 to 9. All these ester derivatives formed a thermotropic cholesteric liquid crystal. The temperature dependence of the cholesteric pitch was studied and discussed in relation to the side-chain length and molecular weight.
