Poly(tert-butyl acrylate)-coupled cyclophane was obtained by coupling 1,6,20,25-tetraaza[6.1.6.1]paracyclophane with carboxyl-terminated poly(fert-butyl acrylate). The poly(tert-butyl acrylate) was quantitatively hydrolyzed to poly(acrylic acid). The cyclophane carrying poly(acrylic acid) was soluble in alkaline water and formed an inclusion complex with trimethyl-2-naphthylmethylammonium bromide as a guest.
