| Abstract: | In this work, we have developed an easy approach for vinylene-linked ion-in-conjugation porous polymer networks (IIC-PPN) using Knoevenagel polycondensation of predesigned zwitterionic N-(3-sulfopropyl)-2,6-(dimethyl)pyridinium salt and 1,3,5-triformylbenzene as monomers. The resulting IIC-PPNs exhibit a porous morphology with high specific surface areas up to 263 m2·g-1. Although the IIC-PPN network contains arylene-vinylene nodes that make it apolar, the incorporation of zwitterionic pyridinium building blocks enable a significant ionic dipole, which is reflected in the water uptake of 14.5 g·g-1, which is higher than that of similar poly(arylene-cyano-vinylene)s with 7.0, 8.5 and 5.3 g·g-1 for PAV–CN, PAV–OMe, and PAV–CHO, respectively. The IIC-PPNs exhibit significant semiconducting properties with optical absorption band edges of 512 nm and an electrochemical band gap of 2.55 eV. The intriguing properties of IIC-PPN prompted us to use them as heterogeneous photocatalysts to photooxidize the endocrine disrupting compound bisphenol A (BPA) dissolved in water under visible light. |
