Summary: Conjugated porous polymers (CPPs) are a new family of functional porous materials with tuneable porosities and molecular architectures, showing great potentials in adsorption, light harvesting, and catalysis applications. This study describes the incorporation of strong visible-light absorbing BODIPY molecules into the skeleton of CPPs, resulting in CPPs with integrated properties of high surface area, hierarchical porous structures, and strong visible-light absorption. The obtained CPPs demonstrated relatively high adsorption capacity and high photocatalytic degradation efficiency towards organic dyes, with mechanism studies revealing the generation of singlet oxygen species as the main driving force for the dye degradation.

Summary: In this study, trisphloroglucinol substituted triazine was used as a building block to construct hypercrosslinked polymers for the removal of organic micropollutants from water. These polymers exhibited hierarchical porous structure, high degree of functionality, and good hydrophilicity. The embedded trisphloroglucinol skeletons enabled effective adsorption of various cationic and nonionic organic micropollutants. The adsorption capacity and rate of the polymers were superior to previously reported adsorbent materials. Additionally, the polymers could be easily reused multiple times without a significant decrease in adsorption efficiency, making them suitable for wastewater treatment.

Summary: In recent years, porous hybrid polymers have shown promising prospects in environmental restoration due to their excellent comprehensive performances. Two types of porous silsesquioxane/triazine hybrid polymers were synthesized through the Friedel-Crafts reaction using different ratios of phenyl- or thiophene-substituted triazine monomers and octavinylsilsesquiox-ane (OVS). The adsorption capacities of the polymers for dyes and iodine vapor were investigated, with PCS-TPH exhibiting higher absorption capacities for large-sized Congo Red (CR) and rhodamine (RB) and both PCS-TPH and PCA-TSA showing similar adsorption amounts for iodine vapor. The materials also demonstrated specific response to iodine among different types of anions due to charge transfer effects.

Summary: Porous organic polymers incorporating nitrogen-rich functionalities have shown great potential for efficient CO2 capture and separation. In this study, two-dimensional azo-bridged porous organic polymers based on benzene and triazine were synthesized and characterized. The synthetic methods and building units were found to significantly affect the porosity of the resulting polymers. Computational simulations suggested that the length of linear linkers did not affect CO2 adsorption properties.

Summary: Two novel conjugated porous polymers (CPPs) with pyrene and 1,3,5-triazine building blocks were synthesized. Structural changes in the peripheral groups of the triazine units greatly affected the photocatalytic activity of the polymers. The catalyst containing thiophene-triazine (ThPy-CPP) showed a much higher photocatalytic hydrogen evolution rate than the one containing phenyl-triazine (PhPy-CPP), indicating a promising direction for designing efficient CPP-based photocatalysts.

Summary: This report describes the development of two triazine- and dithienothiophene-based conjugated microporous polymer (CMP) photocatalysts, TzDTT and TzDTDO. It was found that TzDTT possesses stronger electron donor-acceptor ability but a lower photocatalytic hydrogen evolution reaction (HER) rate compared to TzDTDO. The sulfone groups in TzDTDO were found to play a key role in its superior photocatalytic activity.
