Abstract
The invention relates to compounds of formula I:x+y+z=1 and x=0 to 1, y=0 to 1, z=0 to 1 and R is CH3 or CF3 and R1 and R2 each represent H or a functional group. These compounds show promise in films and as optical waveguide materials as well as bimodal interference coupler and arrayed waveguide grating demultiplexer materials.
