Facile synthesis of a triptycene-based porous organic polymer with a high efficiency and recyclable adsorption for organic dyes

Water contamination resulting from organic dyes has had severe detrimental effects on human health and environmental tolerance. To address this issue, a delicate strategy for taking host-guest function in porous organic polymers via a facile Friedel-Crafts reaction of triptycene and post-modification was achieved. By means of this route, a sulfonic acid functionalized triptycene-based porous organic polymer (TPOP-SO3H) with a hierarchical structure and a desirable Brunauer-Emmett-Teller value of 1002 m(2)/g was synthesized this study. The TPOP-SO3H material demonstrated a maximum adsorption capacity for methylene blue of 97.1 mg/g. Remarkably, an absorption efficiency of more than 90% of TPOP-SO3H was observed even after five cycles. Therefore, such a hierarchical porous organic polymer can be highly recommended as one type of promising material for the treatment of organic dye-polluted wastewater.
