Two new pyrene-cored covalent organic polymers (COPs), and , were synthesized via the one-step polymerization of two thiophene-based isomers, 1,3,6,8-tetra(thiophene-2-yl) pyrene ( ) and 1,3,6,8-tetra(thiophene-3-yl) pyrene ( ). The resulting pyrene-cored COPs exhibit rather different surface areas of 54 m g and 615 mg for and , respectively. The CO uptake capacities of and also show different values of 2.85 and 9.73 wt % at 273 K, respectively. Furthermore, offers not only a larger CO adsorption capacity but also a better CO/CH selectivity at 273 K compared with . and also exhibit considerable differences in their photophysical property. The different structure and properties of could be attributed to the isomer effect of their corresponding thiophene-based monomers. © 2017 Authors.
