Patent ID: 8373158

Claim:
A surface modifying agent comprising a compound represented by the following Chemical Formula 1: wherein, in the above Chemical Formula 1, L is selected from the group consisting of a C 1 to C 30 alkylene group, a C 1 to C 30 perfluoroalkylene group, a linker represented by the following Chemical Formula 1a, an aromatic group, a heterocyclic group, an amine group, an amide group, an ester group, and combinations thereof, wherein, in the above Chemical Formula 1a, A is selected from the group consisting of O, S, NR 1 , NHCO, SO 2 , COO, and CO, wherein R 1 is hydrogen or a C 1 to C 3 linear or branched alkyl group, m is an integer ranging from 1 to 3, and n is an integer ranging from 1 to 30, X is selected from the group consisting of a functional group represented by the following Chemical Formula 1b to Chemical Formula 1d, SH, CONHOH, COON, OH, COSH, COSeH, SeH, SO 3 H, CN, an amino group, and a phosphinyl group, wherein, in the above Chemical Formula 1b, D 1 and D 2 are the same or different from each other, and are independently selected from the group consisting of a halogen, a C 1 to C 3 linear or branched alkoxy group, and OH, wherein, in the above Chemical Formula 1c, D 3 and D 4 are the same or different from each other, and are independently selected from the group consisting of a halogen, OH, a C 1 to C 3 linear or branched alkoxy group, and NR 2 R 3 , wherein R 2 and R 3 are the same or different from each other and are independently a C 1 to C 3 linear or branched alkyl group, and wherein, in the above Chemical Formula 1d, D 5 to D 7 are the same or different from each other, and are independently selected from the group consisting of a halogen, OH, a C 1 to C 3 linear or branched alkoxy group, and a C 1 to C 3 linear or branched alkyl group, provided that D 5 to D 7 are not simultaneously an alkyl group.
