| titleOfInvention | Fluorine-substituted polyaryl ether for optical device, method for manufacturing same, and optical waveguide type optical device using same |
| abstract | The present invention relates to a fluorine-substituted polyarylene ether having an acryl group or cinnamil group represented by the following formula (1), a method for producing the same, and an optical waveguide optical device using the fluorine-substituted polyarylene ether. Fluorine-substituted polyarylene ether derivatives are obtained by thermal condensation polymerization of decapulurobiphenyl or decapulurobenzophenone and aromatic diol, and the polymer for the optical waveguide device of the present invention is introduced by introducing an acryl group or cinnamil group into these polymers. To prepare. The polymer has a very low optical propagation loss, which is the biggest problem of the polymer optical device by excluding the light absorption in the intrinsic optical communication region due to molecular vibration by high fluorine substitution in the main chain structure. In addition, by introducing a photocurable acrylic group or cinnamil group into the polymer terminal or polymer side chain, the chemical resistance through photocrosslinking of the polymer matrix can be improved to enable a multilayer membrane process, and thermal stability that does not thermally decompose and sublimate even at temperatures above 300 ° C. Excellent optical waveguide type optical device can be manufactured.n n n [Formula 1]n n n n n n n n Wherein X is absent or -C = 0- or -SO 2- .
