Claim Text:
1. A method for binding an IgG-Fc or an Fc fusion protein to a low-molecular-weight compound, comprising contacting a low-molecular-weight compound represented by the general formula (I): wherein ArX is a structure containing an optionally substituted aromatic six-membered ring, ArYHB is a structure containing an optionally substituted aromatic six-membered ring having a proton donor, the atom group “Linker” is a structure containing optionally substituted tetrazole, optionally substituted hydantoin, optionally substituted pyrrol, optionally substituted pyridine, optionally substituted 1,3,4-thiadiazole, optionally substituted triazole, optionally substituted aminopyrazolo[3,4-d]pyrimidine, optionally substituted thiazole or nitropyrimidine, or is represented by —U—CZ—V—, wherein CZ is a structure containing an optionally substituted benzene ring or an optionally substituted naphthalene ring, and U and V are respectively composed of a non-hydrogen atom not containing a ring structure and binds ArX with ArYHB, with the IgG-Fc or Fc fusion protein.
