New liquid‐crystalline polyesters and paramagnetic vanadyl complex were prepared as host polymer and guest complex. Melt‐drawn fibers were made from the blend of host polymer and guest complex at the mesophase temperature. ESR spectra of the melt‐drawn fibers indicated that the base of pyramidal vanadyl complex is completely oriented parallel to the fiber axis.
