A chiral polymer comprising a repeat unit having a first planar group disposed in a first plane; a second planar group disposed in a second plane different from the first plane; a bond or group linking the first planar group and the second planar group; and a first divalent binding group linking the first planar group and the second planar group. The polymer may be used as the active material of an electrooptic modulator.

Various routes were examined for the synthesis of chiral biphenyl species that are substituted at the 2,2‘, 4,4‘ and 6,6‘ positions. Because the biaryl bond is tetrasubstituted, many coupling reactions were not suitable. The most reliable coupling reaction proved to be the Ullmann, which gave the desired product in 82% yield. The products were required as the starting point for the preparation of chiral
