Patent ID: 7867391

Claim:
A cucurbituril derivative-bonded solid substrate in which a cucurbituril derivative of Formula 1 below is covalently bonded to a modified solid substrate of Formula 2 below: wherein n is an integer of 4 to 20, and R1 and R1′ are each independently an alkenyloxy group with an unsaturated bond end and a substituted or unsubstituted alkyl moiety of C 1 -C 20 , a carboxyalkylsulfinyloxy group with a substituted or unsubstituted alkyl moiety of C 1 -C 20 , a carboxyalkyloxy group with a substituted or unsubstituted alkyl moiety of C 2 -C 8 , an aminoalkyloxy group with a substituted or unsubstituted alkyl moiety of C 2 -C 8 , or a hydroxyalkyloxy group with a substituted or unsubstituted alkyl moiety of C 2 -C 8 , and wherein R 2 is an alkyl group of C 1 -C 10 with an end functional group selected from thiol, amine, epoxy, isocyan, and isothiocyan.
