Abstract:
Herein, an ultramild block polymerization strategy was employed to precisely control the exposure of structural terminations in the skeleton of covalent triazine-based frameworks (CTFs). The generated structural terminations with cyano (-CN) and hydroxy (-OH) groups (STCHs) could serve as not only the optimal adsorption sites for enriching targets, but also π-conjugated electron donor-acceptor dyads to accelerate the charge transfer. With spatial separation of charge localization sites, STCH-CTF exhibited a photoactivity of 2.5-4 times higher than that of pristine CTFs in the simultaneous oxidation of bisphenol A (BPA) and the reduction of hexavalent chromium (Cr(vi)).
