Porphyrin-Based Covalent Triazine Frameworks: Porosity, Adsorption Performance, and Drug Delivery

Two porous porphyrin-based covalent triazine frameworks (PCTFs), in which porphyrin is incorporated as building block, have been synthesized by the Friedel-Crafts reaction. The copolymer PCTFs show large Brunauer-Emmett-Teller specific surface area of up to 1089 m(2) g(-1), high CO2 uptake capacity reaching 139.9 mg g(-1) at 273 K/1.0 bar, and good selectivity for CO2/CH4 adsorption attaining 6.1 at 273 K/1.0 bar. The resulting porous solids also can be used as matrices for drug delivery of ibuprofen in vitro. (C) 2017 Wiley Periodicals, Inc.
