Optical waveguide fabrication using a polymeric azine containing the 3-dodecylthiophene moiety

New polymeric azines, DOZ and DOPh, containing the 3-dodecylthiophene moiety, have been obtained by the condensation reactions of 2,5-diformyl-3-dodecylthiophene with hydrazine and p-diaminobenzene, respectively. Their average molecular masses depend on the preparation conditions. Using DOZ polymers, which are completely soluble in common organic solvents, we were able to demonstrate channel waveguide formation and function. The waveguide losses could be separated into intrinsic absorption losses and scattering contributions.
