Preparation of Stable Photopatternable Polymeric Materials for Non-linear Optics

摘要

Several new functionalized chromophores have been prepared and tested in thepreparation of optically stable, photopatternable, NLO polymers for second harmonic generation at the diode laser wavelength of 820 nm. In particular, chromophores containing the sulfonamide or sulfonate ester functionalities have been found to be extremely versatile as they allow attachment of a polymerizable group at the electron-poor end of NLO chromophores. The results of model studies confirm that the sulfonamide groups do not have a deleterious effect on NLO
