Claims21
A photoactive compound represented by Formula 1,
- wherein, in Formula 1,
- Y is a C1-C15 alkylene group unsubstituted or substituted with one or more substituents selected from the group consisting of R, OR, SR, COR and OCOR,
- M1 is a C1-C8 alkyl group or a C6-C12 aryl group,
- R1 is a C1-C8 alkyl group or a C6-C12 aryl group,
- at least one of R2 to R6 is XA, and the rest are each independently selected from the group consisting of a halogen group, CN, R, OR, SR, COR, OCOR, NRR′ and CONRR′,
- X is directly linked;
- or selected from the group consisting of C═O, O, S, S═O, and SO2,
- A is a C6-C20 aryl group unsubstituted or substituted with one or more substituents selected from the group consisting of a halogen group, CN, R, OR, SR, COR, OCOR, NRR′ and CONRR′,
- R and R′ are each independently selected from the group consisting of hydrogen, a C1-C10 alkyl group, a C1-C10 haloalkyl group and a C7-C13 arylalkyl group, or R and R′ may form a ring together.
