Abstract Rising carbon dioxide (CO 2 ) levels in the atmosphere are recognized as a threat to atmospheric stability and life. Although this greenhouse gas is being produced on large scale, there solutions reduction indeed utilization of gas. Many these involve costly or unstable technologies, such air‐sensitive metal–organic frameworks (MOFs) for CO capture “non‐green” systems amine scrubbing. Conjugated microporous polymers (CMPs) represent simpler, cheaper, greener solution utilization. They often easy synthesize at scale (a one pot reaction many cases), chemically thermally stable (especially comparison with their MOF covalent organic framework (COF) counterparts, owing amorphous nature), and, result, cheap manufacture. Furthermore, surface areas, tunable porous chemical structures mean they reported highly efficient motifs. In addition, provide dual pathway utilize captured via conversion electrochemical into industrially valuable products. Recent studies show that all attractive properties can be realized metal‐free CMPs, presenting truly green option. The promising results two fields CMP applications reviewed explored here.

Various energy storage systems widely utilize conjugated microporous polymers (CMPs) due to their porous architecture and expansive surface area, which facilitate efficient ion transport storage. In our research, we developed two anthraquinone (ATQ)-based CMPs (ATQ-CMPs) through a Sonogashira coupling method. We used 2,6-dibromoanthraquinone (ATQ-Br2), redox-active precursor, as building monomer along with an ethynyl derivative of triphenylamine (TPA-T) tetrabenzonaphthalene (TBN-T) afford TPA-ATQ CMP TBN-ATQ CMP, respectively. employed techniques, such thermogravimetric analysis, high-resolution transmission electron microscopy (HR-TEM), scanning (SEM), Fourier-transform infrared spectroscopy (FTIR), characterize the structure thermal properties these ATQ-CMPs.

Electrorheological fluids (ER) make up a class of smart materials that are distinguished by their capacity to alter rheological characteristics in controlled and reversible manner response an externally applied electric field (E). As inherent polarizable anhydrous ER-active material, polyaniline (PAni)-based among the most frequently utilized materials.
