A simple methodology to controllably tune the pore size and Cr(VI) adsorption capacity was reported herein synthesize a new series of conjugated microporous polyaniline (CMPA) networks. The well-ordered micropore acquired through our very recent Bristol-Xi'an Jiaotong method, fine-tuned increase with increasing length linkers, mimicking covalent organic frameworks metal much. selective ultrahigh 520.8 mg/g achieved by CMPA-1 in fast manner, systematically gradual decrease 173.9 CMPA-3 enlarging networks, featuring tunable molecular-size-recognition mechanism. Additionally, robust CMPA which were constructed Buchwald-Hartwig chemistry, showed complete function capable providing, besides large storage for Cr(III), at least 10 reductant/desorption-free cycles effective reduction detoxication their novel self-reducible redox states. Outcomes that CMPAs could be applied as self-healing scavengers next generation detoxication.
