Disclosed are a monomer for a polymer gel, a polymer gel and a preparation method therefor. The preparation method includes: reacting 4,4,4-trihydroxytriphenylmethane with tert-butyldimethylchlorosilane to obtain TPC-OTBS; reacting 4,4,4-trihydroxy triphenylmethane with sulfuryl fluoride in the presence of triethylamine to prepare TPC-OSO.sub.2F; and dissolving the TPC-OTBS and TPC-OSO.sub.2F in DMF, then adding DBU and ultrasonically dispersing same until uniform, and letting same stand to obtain a polymer gel. The gel obtained by the present invention can selectively adsorb an organic solvent by means of electrostatic interaction and Van der Waals force. The surface and internal morphologies of a solid material are characterized by SEM and TEM, in which the porous morphology of the solid material is found, and most of the pores are macropores.
