Special Issue Information

Dear Colleagues,

Porous polymer materials have drawn much research enthusiasm for their characteristics of light weight, designable composition, inherent porosity, and so forth. Porous organic polymers are typical representatives of porous polymer materials which are linked by stable covalent bonds and easy to function. It is of great significance to select appropriate protocols to afford functional porous organic polymers and investigate the structure–activity relationship. The pre-designable "bottom–up" strategy and post-modified "top–down" method are conventional ways to achieve functional porous organic polymers with specific function. Further research on functional porous organic polymers is beneficial to promote the practical application of this ideal platform in energy storage, photo-/electro-catalysis, sensor, etc.

This Special Issue of Polymers aims to report recent progress in the field of functional porous organic polymers. Porous organic polymers applied in energy storage/transfer, photo-/electro-catalysis, selective adsorption, and so forth, and novel synthetic strategy for functional porous organic polymers are significant contents of this Special Issue. Original and innovative articles, communications, and reviews on this topic are encouraged and welcomed to submit.

In this study, a series of highly crystalline π-conjugated polyimide photocatalysts with porous nano hollow shell (HSPI) was prepared for the first time by the hard template method by adjusting the addition ratio of the template precursor. SiO2 nanospheres not only serve as template agents but also as dispersants to make precursors of SPI more uniform, and the degree of polymerization will be better, resulting in significantly enhanced crystallinity of HSPI relative to bulk SPI (BSPI). More strikingly, it is found that HSPI has a larger specific surface area, stronger visible light absorption, and higher separation efficiency of photogenerated electron and hole pairs compared with BSPI by various spectral means characterization analysis. These favorable factors significantly enhanced the photocatalytic degradation of methyl orange (MO) by HSPI. This work provides a promising approach for the preparation of cheap, efficient, environmentally friendly, and sustainable photocatalysts. Full article

Covalent organic frameworks (COFs) with donor–acceptor (D–A) units are credible photocatalysts for their per-designed structure, inherent porosity, large surface area, splendid stability and so forth. Developing COFs with an excellent photocatalytic efficiency for hydrogen evolution is of a great significance in alleviating the energy crisis. Herein, a D–A type imine-linked crystalline Zn-Por-TT COF was fabricated successfully via the co-polymerization of electron-deficient Zinc (II) 5,10,15,20-tetrakis(para-aminophenyl) porphyrin (Zn-TAPP), and electron-rich thieno[3,2-b]thiophene-2,5-dicarbaldehyde (TT). Profiting from the D–A complex structure, the obtained Zn-Por-TT COF showcases an excellent photocatalytic activity with a hydrogen evolution rate of 8200 μmol/g/h, while the Zn-TAPP monomer presents practically no capacity for the generation of hydrogen under identical conditions. In addition, the counterparts Por-TT COF and COF-366-Zn were employed to illustrate the enhancement of the photocatalytic performance by metal catalytic sites and D–A structures. In addition, the counterparts Por-TT COF and COF-366-Zn were employed to illustrate the enhancement of metal catalytic sites and D–A structures for the photocatalytic performance. Full article
