| titleOfInvention | New nonlinear optical polymer with excellent thermal stability |
| abstract | 1. Technical field to which the invention described in the claims belongsn n n The present invention relates to a novel nonlinear optical polymer which is used as an optical material and has excellent thermal stability.n n n 2. Technical Challenges to be Solved by the Inventionn n n It is intended to provide a new nonlinear optical polymer improved in glass transition temperature so as to prevent the degradation of nonlinear optical properties due to disordered order of optical characteristics at low temperatures.n n n 3. The point of the solution of the inventionn n n There is provided a polymer of the following general formula (I).n n n n n n n n In the above general formula (I), -A represents to be.n n n R 1 is -O- (CH 2 ) l -O- (wherein l is an integer from 1 to 20), -S- (CH 2 ) m -S- (m is an integer of 1 to 6 or 8 or 9 essence, (n is an integer from 1 to 3 and Y is H or CH 3 ), or (p is an integer from 1 to 6 and Y is H or CH 3 ).n n n R 2 is to be.n n n Wherein Q is Cl, Br, I, ego;n n n R is an alkyl group having 1 to 20 carbon atoms.n n n And Z is a bidentate unit.n n n 4. Important Uses of the Inventionn n n The novel nonlinear optical polymer having excellent thermal stability of the present invention is used as an optical material such as an optical switch, an optoelectronic material, and an optical storage element. |
