Polymers of intrinsic microporosity (PIMs), with an interconnected microporous network, high surface area, and structural diversity, have attracted great interest in developing diverse materials for various applications in the fields of environmental remediation, gas and liquid separation, sensors, and energy. Solution-processable PIMs can be transformed into various robust functional materials, including films, membranes, coatings, and fibers, that can be applied to address different industrial challenges. Since the first PIM synthesis, great strides have been made in expanding the structural diversity of PIMs by designing fine-tuned PIMs for various applications. This review provides a general overview of PIMs, from their synthesis to their involvement in state-of-the-art applications such as water and air filtration, gas and liquid separation, catalysis, sensing, and energy applications, during the last decade. Several PIMs have exhibited outstanding performance in oil adsorption, gas separation, and catalysis. In this context, PIMs' functionality and porosity are key parameters that must be controlled to tailor PIMs for broader applications. Overall, this review provides a comprehensive overview of PIMs from chemistry to applications and highlights the challenges and prospects of the next generation of PIM-based functional materials that will open new avenues for adsorption, gas separation, and filtration applications.

“…18,19 PIMs have been extensively employed to prepare separation membranes, 20,21 catalysts, 22,23 and adsorbents. 24,25 Consequently, we speculate that PIMs may be good templates to bundle azo for preparing high-performance flexible PSTFs due to the combination of rigid backbones, good processability, and high intrinsic microporosity. Herein, we report a convenient route to prepare PIM-based PSTFs for the first time, which just involves two simple reactions from commercial reactants (Scheme 1).…”

Polymer-based solar thermal fuels (PSTFs) have great potential in flexible thermal management devices; however, it is a challenge to simultaneously realize both high gravimetric energy density (ED g ) and good processability. Herein, we report a convenient route to prepare PSTFs with improved ED g and good processability by using 4-bromomethylazobenzene (Azo-Br) to quaternize polymers of intrinsic microporosity. The as-prepared Azo-PDAT possesses a high ED g of 180.2 J g −1 , and its azo moiety has an energy storage enthalpy (ΔH) of 272.1 kJ mol −1 , which are 4.4 and 23.9 times higher than those of parent Azo-Br, respectively. In comparison, Azo-MTLE shows a relatively low ED g of 129.8 J g −1 due to the hindrance of photoisomerization by the relatively flexible polymer backbones and decreased micropores. Furthermore, Azo-DDM was synthesized to represent a repeat unit of the as-prepared PSTFs and exclude micropores and polymer backbones, demonstrating the cation−π interactions for enhancing energy storage. Hence, the improved ED g of Azo-PDAT is attributed to the synergetic effect of cation−π interactions, intrinsic microporosity, and template-enforced steric strain. Both Azo-PDAT and Azo-MTLE show good processability for the success of electrospinning. The robust cyclability and macroscale heat-release with a temperature difference of 6.6 °C were achieved for Azo-PDAT, exhibiting good prospects in intelligent temperature-controlled fabrics.
