wherein, in the general formula (1), R 1 and R 2 are each independently selected from a substituted or unsubstituted alkyl group having 1 to 10 carbon atoms, and a substituted or unsubstituted alkylene group having 1 to 8 carbon atoms, the alkylene group having a polymerizable functional group, and R 3 to R′ 2 are each independently selected from a hydrogen atom, a cyano group, a trifluoromethyl group, a substituted or unsubstituted alkyl group, a substituted or unsubstituted alkylene group having a polymerizable functional group, and a polymerizable functional group, provided that at least one of R 3 to R 12 represents an electron-withdrawing group, and at least one of R 1 to R 12 has a polymerizable functional group.

2. The optical element according to claim 1 , wherein the polymerizable functional group comprises an acryloyloxy group, a methacryloyloxy group, a vinyl group, or an epoxy group.

3. The optical element according to claim 1 , wherein at least one of R 5 , R 6 , R 9 , or R 10 represents an electron-withdrawing group, and the electron-withdrawing group comprises a cyano group or a trifluoromethyl group.

4. An optical apparatus comprising the optical element according to claim 1 .

5. The optical apparatus according to claim 4 , wherein the optical element comprises a lens and the optical apparatus comprises a camera.

6. The optical element according to claim 1 , wherein a content of the polymer obtained by subjecting the compound represented by the general formula (1) to homopolymerization or copolymerization in the optical member is 1.0 wt.% to 99 wt.%.

7. The optical element according to claim 1 , wherein a content of the polymer obtained by subjecting the compound represented by the general formula (1) to homopolymerization or copolymerization in the optical member is 50 wt.% to 99 wt.%.

8. The optical element according to claim 1 , wherein the optical member contains a resin, and
wherein a content of the resin in the optical member is 0.01 wt.% to 99 wt.%.

9. The optical element according to claim 1 , wherein the optical member contains a resin, and
wherein a content of the resin in the optical member is 0.01 wt.% to 50 wt.%.

10. A material comprising a polymer obtained by subjecting a compound represented by general formula (1) to homopolymerization or copolymerization:

wherein, in the general formula (1), R 1 and R 2 are each independently selected from a substituted or unsubstituted alkyl group having 1 to 10 carbon atoms, and a substituted or unsubstituted alkylene group having 1 to 8 carbon atoms, the alkylene group having a polymerizable functional group, and R 3 to R 12 are each independently selected from a hydrogen atom, a cyano group, a trifluoromethyl group, a substituted or unsubstituted alkyl group, a substituted or unsubstituted alkylene group having a polymerizable functional group, and a polymerizable functional group, provided that at least one of R 3 to R 12 represents an electron-withdrawing group, and at least one of R 1 to R 12 has a polymerizable functional group.

11. The material according to claim 10 , wherein the polymerizable functional group comprises an acryloyloxy group, a methacryloyloxy group, a vinyl group, or an epoxy group.

12. The material according to claim 10 , wherein at least one of R 5 , R 6 , R 9 , or R 10 represents an electron-withdrawing group, and the electron-withdrawing group comprises a cyano group or a trifluoromethyl group.

13. A compound represented by general formula (1):

wherein, in the general formula (1), R 1 and R 12 are each independently selected from a substituted or unsubstituted alkyl group having 1 to 10 carbon atoms, and a substituted or unsubstituted alkylene group having 1 to 8 carbon atoms, the alkylene group having a polymerizable functional group, and R 3 to R 12 are each independently selected from a hydrogen atom, a cyano group, a trifluoromethyl group, a substituted or unsubstituted alkyl group, a substituted or unsubstituted alkylene group having a polymerizable functional group, and a polymerizable functional group, provided that at least one of R 3 to R 12 represents an electron-withdrawing group, and at least one of R 1 to R 12 has a polymerizable functional group.

14. The compound according to claim 13 , wherein the polymerizable functional group comprises an acryloyloxy group, a methacryloyloxy group, a vinyl group, or an epoxy group.
