Abstract
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.
Claims21
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.
A chiral monomer of formula (I′) or (II′) or (III):
- wherein Ar1 is an arylene or heteroarylene group which is unsubstituted or substituted with one or more substituents and which is disposed in a first plane;
- Ar2 is an arylene or heteroarylene group which is unsubstituted or substituted with one or more substituents and which is disposed in a second plane different from the first plane;
- B1 in each occurrence is independently a divalent binding group;
- B2 in each occurrence is independently a divalent binding group;
- LG1 in each occurrence is independently a leaving group;
- and LG2 in each occurrence is independently a leaving group.
An electrooptic modulator comprising a polymer film and electrodes for applying an electric field across the polymer film wherein the polymer film comprises a chiral polymer.
