Claim:
A benzophenone compound of formula (1) below: wherein Y 1 is one selected from the group consisting of a H, a OH, an N(R 1 )(R 2 ), a SH, and a substituted or unsubstituted C 1 –C 30 heteroalkyl group; each of Y 2 and Y 3 is independently selected from the group consisting of a H, a OH, an N(R 1 )(R 2 ), a SH, a substituted or unsubstituted C 1 –C 30 alkyl group, a substituted or unsubstituted C 1 –C 30 alkenyl group, a substituted or unsubstituted C 1 –C 30 alkynyl group, a substituted or unsubstituted C 1 –C 30 heteroalkyl group, a substituted or unsubstituted C 6 –C 30 aryl group, a substituted or unsubstituted C 7 –C 30 arylalkyl group, a substituted or unsubstituted C 3 –C 30 heteroaryl group, and a substituted or unsubstituted C 4 –C 30 heteroarylalkyl group; X is selected from the group consisting of a substituted or unsubstituted C 1 –C 30 alkylene group, a substituted or unsubstituted C 1 –C 30 alkenylene group, a substituted or unsubstituted C 1 –C 30 alkynylene group, a substituted or unsubstituted C 1 –C 30 heteroalkylene group, a substituted or unsubstituted C 6 –C 30 arylene group, a substituted or unsubstituted C 7 –C 30 arylenealkylene group, a substituted or unsubstituted C 3 –C 30 heteroarylene group, and a substituted or unsubstituted C 4 –C 30 heteroarylenealkylene group; Y is a linker selected from the group consisting of —O—, —CO—, —NR 1 —, —N═N—, —S—, —NH—, —CH═CH—, —C≡C—, —C(═O)NR 1 —, —NR 1 CO—, —SO 2 —, —SO 3 —, —COO—, —OCO—, —C(═S)—O—, —OC(═S)—, —CO—O—CO—, —CO—S—CO—, —CO—NR 1 —CO—, —C(═S)—O—C(═S)—, —C(═S)—S—C(═S)—, —C(═S)—NR 1 —C(═S)—, —NHCO—R 3 —COO—, —OCO—R 3 —CONH—, —OCO—R 3 —COO—, —O—P(═O)(OH)—O—, and —O—P(OH)—O—; and Z is a moiety of one of formulas (2) and (3) below: wherein each of R 1 and R 2 is independently one of a hydrogen atom and a C 1 –C 6 alkyl group; n is an integer from 0 to 6; R 3 is selected from the same group for said X; each of a, b, and c is independently an integer from 1 to 20; each of R 4 and R 5 is independently a C 1 –C 10 alkyl group; each of R 6 and R 7 is independently one of a hydrogen atom and a methyl group; R 8 is one of a substituted or unsubstituted C 1 –C 20 alkylene group and a substituted or unsubstituted C 6 –C 20 arylene group; W is one of —COOH, —NH 2 , and —OH; and each of k and l is independently an integer from 1 to 10.
