Liquid crystalline polyetheresters with crown ethers in the mesogenic unit have been synthesized using the DB-[ 181-C-6 crown. This compound was then transferred to the diacetyl-, dicarboxy-and dicarboxydichloride derivatives. After incorporation of the crown ether moiety into the mesogens of main c
