Optical organic-inorganic waveguide materials were synthesized by non-hydrolytic sol-gel reaction. To synthesize an alkoxysilane precursor, 3-glycidoxypropyl trimethoxysilane was reacted with azo-type materials at elevated temperature. This precursor was then reacted with 4,4’-(hexafluoroisopropylidene)diphenol to synthesize the organic-inorganic hybrids by sol-gel reaction. The reaction mixture was then heat-treated for thermal condensation and methanol as a byproduct was also eliminated. After product has added 2,2-dimethoxy-2-phenylacetophenone for using UV-curing, the thin film was prepared by spin coating or bulk dropwise methode on the ITO substrate. It was cured by UV-curing methode and their patterned morphology and electro-optical properties were precisely measured. Also, E-beam process was used another cuing methode. This process was more efficient curing methode than UV-curing methode. Because E-beam was very short curing time and very strong irradiation power. |
