Patent ID: 8642991

Claim:
A photosensitive quantum, dot comprising: a quantum dot; and a plurality of photosensitive moieties that are bound to a surface of the quantum dot, wherein each of the photosensitive moieties comprises silicon and a photosensitive functional group, wherein each of the photosensitive moieties is represented by a formula selected from the group consisting of Formula 1 and Formula 2: wherein * is a binding site with the surface of the quantum dot; L 1 and L 2 are each independently a linking group selected from the group consisting of —S—, —R 1 —S—, —N═C—, —R 1 ═N—, —OOC—, —R 1 —OOC— and —O—POOR 1 R 2 —, wherein R 1 and R 2 each independently hydrogen or —(CH 2 ) p —, and p is an integer in the range of 1 to about 10; Q 1 through Q 6 are each independently a single bond or a linking group of —[C(R 3 )(R 4 )] q —, wherein R 3 and R 4 each independently hydrogen, a C 1 -C 20 alkyl group, or —OH, wherein at least one of the —C(R 3 )(R 4 )— groups is replaced with a group selected from the group consisting of —COO—, —NHCO—, —OCO—, —O— and —S—, wherein q is an integer in the range of 1 to about 20; T 1 is a photosensitive functional group that is photocrosslinkable or photocurable upon exposure to light; T 2 through T 4 are each independently selected from the group consisting of hydrogen, a substituted or unsubstituted C 1 -C 20 alkyl group, a substituted or unsubstituted C 2 -C 20 alkenyl group, a substituted or unsubstituted C 6 -C 14 aryl group and a photosensitive functional group that is photocrosslinkable or photocurable upon exposure to light, wherein at least one of T 2 through T 4 is a photosensitive functional group that is photocrosslinkable or photocurable upon exposure to light, and a substituent of the C 1 -C 20 alkyl group, C 2 -C 20 , alkenyl group and C 6 -C 14 aryl group is selected from the group consisting of a hydroxyl group, a halogen atom, an amino group, a thiol group, a C 1 -C 10 alkyl group and a C 6 -C 14 , aryl group; *′ is a binding site between a first photosensitive moiety of Formula 1 and a silicon of an adjacent photosensitive moiety represented by Formula 1; *″ is a binding site between a first photosensitive moiety of Formula 1 and an oxygen of an adjacent photosensitive moiety represented by Formula 1; and wherein the photosensitive functional group is represented by Formula 3: —CR 5 ═CR 6 R 7 Formula 3 wherein R 5 through R 7 are each independently represented by one selected from the group consisting of hydrogen, a C 1 -C 10 alkyl group, a C 2 -C 10 alkenyl group, a C 6 -C 10 aryl group, a C 1 -C 10 alkyl group substituted with at least one selected from a group consisting of a halogen atom, a C 2 -C 10 alkenyl group substituted with at least one of a halogen atom, —CN, —COOH and an amino group.
