“…Organic polymers exhibit varying degrees of light absorption, conjugation, porosity, and hydrophilicity due to their high synthetic tunability. , Metal–organic frameworks (MOFs) have tunable structures and well-dispersed single metal sites. Chen et al used the thermal solvent method to fabricate cobalt tetraminobenzoquinone (Co-TABQ) nanosheets with Co 2+ as the metal nodes, and its band gap was 2.2 eV .…”

Metal−air batteries are a type of electrochemical cell that generates electrical energy by combining metal and oxygen from the air. They are a promising technology for energy storage and portable devices because of their high energy density, low cost, and environmental friendliness. However, the discharge products of these batteries are notoriously difficult to decompose, resulting in a high overpotential. Recent works have shown that semiconductors can capture solar energy and store it in batteries. When exposed to light, photocatalysts generate carriers (strong redox pairs), thereby increasing the electron migration rate and significantly reducing the overpotential of the metal−air battery reaction. Nevertheless, single photocatalysts often exhibit poor cycle performance due to serious carrier recombination. This review paper begins by briefly describing the fundamentals of photoelectrochemistry and then focuses on commonly used photocathode design principles and various reported photocatalysts. It also discusses the main challenges and issues caused by light, such as photocorrosion and electrolyte decomposition. Finally, the critical issues associated with photo electrodes, electrolytes, and electrode/electrolyte interfaces are emphasized, and perspectives on the development of high-performance light-assisted metal−air batteries are presented.

“…22 The pure organic structure endows POPs with unique physicochemical properties, such as good biocompatibility, large specic surface area, high porosity and excellent stability, as well as customizable structure and functionality, which is used in a variety of applications, ranging from environmental to biomedical, gas storage and separation, heterogeneous catalysis, biomedicine, sensing, optoelectronics and energy storage and conversion. [23][24][25][26][27] The localized structural environment provides a precise and accessible void space, which increases reactant exposure on the catalyst surface and thus improves the catalytic efficiency. 28,29 Based on the above characteristics, multiple functional ferrocene-based porous organic polymers with immobilized metal sites can be constructed, conferring peroxidase activity to realize combined therapy.…”

“…Porous organic polymers (POPs) are multidimensional porous network materials built by covalently linking organic building blocks with various geometries and topologies. − Generally, depending on their degree of long-range order, POPs can be divided into two categories, including amorphous conjugated microporous polymers (CMPs), hyper-cross-linked polymers (HCPs), polymers of intrinsic microporosity (PIMs), porous aromatic frameworks (PAFs), and crystalline covalent organic frameworks (COFs) . Being light, porous, stable, and designable, POPs have drawn increasing research interest for wide applications in, e.g., heterogeneous catalysis, photoelectric conversion, chemical- and biosensing, gas storage/separation, and energy storage/conversion. − …”

Two versions of reversed-phase/hydrophilic interaction mixed-mode core–shell stationary phases for high-performance liquid chromatography using porous organic polymers as the shell material were investigated. The stationary phase named SiO2@CTPCC‑TPB using triazine-triphenylbenzene-based porous organic polymers as the shell material has been reported previously. To regulate chromatographic performance, heptazine–biphenyl moieties with fewer benzene rings and higher nitrogen content were used as organic building blocks to grow a porous shell on the surface of silica to acquire a core–shell stationary phase, namely, SiO2@CHPCy‑DB. Various techniques were used to characterize the developed core–shell microsphere, and nonpolar/polar solutes were utilized as probes to investigate the chromatographic behavior of the stationary phase. The results revealed that SiO2@CHPCy‑DB exhibited reversed-phase/hydrophilic interaction mixed-mode with multiple retention mechanisms. Meanwhile, the separation behavior of the two homemade columns and a commercial column was compared to assess the role of the building blocks in porous organic polymers in regulating and improving separation. The successful determination of drugs of abuse in urine via the SiO2@CHPCy‑DB column indicated its potential for the determination of trace analytes in complex samples.
