A porous organic polymer containing pillar[5]arene and 1,3,5-trirthynylbenze(TEB), namely, P[5]-TEB, was synthesized by Sonogashira cross-coupling reaction, then a novel polyhydroxyl polymer P[5]OH-TEB was obtained by demethylation reaction from the former polymer. The physical and chemical properties as well as adsorption properties of the two porous organic polymers were studied. Nitrogen adsorption test showed that the specific surface area of P[5]OH-TEB increased with the introduction of hydroxyl group, and the microporous structure was also introduced. It was indicated by dye adsorption that the adsorption process of the two polymers for methylene blue was consistent with the Langmuir adsorption equation, from which P[5]OH-TEB had a greater adsorption capacity for methylene blue. The adsorption kinetics test indicated that the adsorption process was more suitable for the pseudo-secondary kinetics model and belonged to the chemical adsorption process and P[5]OH-TEB got a faster adsorption rate after modification. It was showed by selectivity adsorption that the polymer can absorb more cationic dyes and the adsorption was decreased to anionic dye after the introduction of hydroxyl group into the polymer.

Key words: porous organic polymers, pillararene, dye absorption
