“…Liao et al proposed a strategy to expand the separation surface area of nanofiltration membranes by grafting highly porous porphyrin–aniline CMP (PACMP) on polyamide. 94 The CMP–polyamide composite membranes were formed by one-step interfacial polymerisation to produce ultra-permeable membranes (61.8 L m −2 h −1 ) with a salt (Na 2 SO 4 ) interception above 91.6%. Moreover, due to the generation of reactive oxygen species from the porphyrin moiety of PACMPs, the photoexcited singlet oxygen ( 1 O 2 ) generated in situ could kill 98.5% of E. coli and 99.7% of S. aureus , which resulted in the excellent antimicrobial performance of the CMP–polyamide composite membrane.…”

“…Ji et al developed a unique synthesis strategy for linking aromatic structural units with phenolic compounds in 2016 . Since then, Azo-POPs with different structures and special functions have been synthesized one after another. − Although the synthesis of azo porous organic polymers has achieved some success, the flexible screening of monomers to synthesize Azo-POPs with certain functions and targeted application in water treatment is still a challenging topic.…”

Effective adsorption and separation of organic pollutants from wastewater are essential to protecting the environment and human health. In this study, porous organic polymers (PAPOPs) containing a tri(polyhydroxy-phenyl-azophenyl) benzene skeleton structure were synthesized through diazotization coupling without any catalyst participation. It was found that PAPOPs have a high specific surface area, a mesoporous structure, a good thermal stability, and electronegativity. Based on these characteristics, PAPOPs demonstrated a maximum adsorption capacity of 1773.15 mg g −1 for rhodamine B (RhB), 1091.75 mg g −1 for Congo red, and 306.33 mg g −1 for tetracycline hydrochloride. Furthermore, PAPOPs also exhibited good selectivity and an extremely fast adsorption rate for RhB. The adsorption efficiency of PAPOPs did not significantly decrease even after seven repeated uses, indicating their broad application prospects in wastewater treatment.

Chemical sensing of harmful species released either from natural or anthropogenic activities is critical to ensuring human safety and health. Over the last decade, conjugated microporous polymers (CMPs) have been proven to be potential sensor materials with the possibility of realizing sensing devices for practical applications. CMPs found to be unique among other porous materials such as metal‐organic frameworks (MOFs) and covalent organic frameworks (COFs) due to their high chemical/thermal stability, high surface area, microporosity, efficient host‐guest interactions with the analyte, efficient exciton migration along the π‐conjugated chains and tailorable structure to target specific analytes. Several CMP‐based optical, electrochemical, colorimetric, and ratiometric sensors with excellent selectivity and sensing performance were reported. In this review, we have comprehensively discussed the advances in CMP chemical sensors with clear segregation of CMP powders as well as thin films in the detection of various analytes such as nitroaromatic explosives, chemical warfare agents, anions, metal ions, biomolecules, iodine, and volatile organic compounds (VOCs), with simultaneous delineation of design strategy principles guiding the selectivity and sensitivity of CMP. Preceding this, various photophysical mechanisms including hybridized local and charge transfer (HLCT) excited state responsible for chemical sensing are also discussed in detail for convenience. Finally, future challenges to be addressed in the field of CMP chemical sensors are discussed.This article is protected by copyright. All rights reserved
