POROUS CARRIER HAVING FORMYL GROUP, ABSORBENT USING THE POROUS CARRIER, METHOD FOR PRODUCTION OF THE POROUS CARRIER, AND METHOD FOR PRODUCTION OF THE ABSORBENT
The present invention relates to a porous base matrix having formyl group, which base matrix has a structure represented by the formula (2) as a spacer, which structure is obtained by cleaving a group represented by the formula (1): wherein, R 1 represents a group forming a five-membered ring or a six-membered ring with -CH (OH) -CH (OH) - a method for producing the porous base matrix and an adsorbent obtained by binding a ligand on the porous base matrix. By the present invention, a high-intensity base matrix for an adsorbent and an adsorbent are provided. The amount of a ligand leaked from the adsorbend is small.
