Polyhedral oligomeric silsesquioxanes (POSS), with unique cage-like three-dimensional (3D) structures, have been considered as promising nanoblocks for novel hybrid porous polymers (HPPs). To date, T 8 POSS-based HPPs have been extensively studied, while the potential of larger POSS remains elusive and intriguing. Herein, we report the synthesis of a series of T 8 , T 10 , and T 12 POSS-based HPPs (T 8 TPM, T 10 TPM, and T 12 TPM) and investigate their size-dictated structure−property relationships. These novel HPPs with identical composition yet distinct framework topologies are available through Friedel−Crafts polymerization of octa-, deca-, and dodeca-vinyl POSS with triptycene in a fixed mass ratio. It is found that the structures and properties of these materials are highly related to the POSS type and, more importantly, display an almost linear increase with increasing POSS size. Specifically, the surface area, pore volume, and adsorption capacity of T 12 TPM are 1214.8 m 2 g −1 , 1.00 cm 3 g −1 , and 4462.4 mg g −1 (Rhodamine B), showing an increase of 13.2, 56.3, and 37.9% compared with T 8 TPM, respectively. These results demonstrate the profound influence of the POSS size on the structure−property relationship of HPPs and could be used to predict the property of larger T 14 , T 16 , and T 18 POSS-based HPPs. This calls for future endeavors in the exploration of larger POSSbased HPPs.

“…The reaction of polyhedral silsesquioxanes and triptycene was first reported by Das et al 50 to synthesize hybrid nanoporous polymers (STNP1, STNP2, STNP3, and STNP4). The as-made STNPs were obtained with varying different ratios of initial monomers based on Friedel−Crafts reaction with a high yield.…”

Since the development of porous materials, porous organic polymers (POPs) have received much attention due to advantages such as attractive architecture, large pore volume, high surface area, and immense porosity. Furthermore, their porous structure can be functionalized with multiple chemical reagents, which will improve their performances in various applications. In the past, significant efforts have been made to synthesize POPs via Friedel–Crafts reaction. It is easy to handle and operates under mild synthesis conditions, requires low reaction temperature, uses considerably less expensive chemicals, and produces high-yield POPs with desirable surface areas. POPs prepared via this method act competitively in various fields. This review focuses on the recent applications of the POPs introduced in gas adsorption and separation, catalyst, water treatment, biomedical, and electrochemical applications, aiming to pave the way for researchers to develop new POPs for modern applications.

“…49,50 On the other hand, the intentional inclusion of triptycene units was expected to provide the required rigidity to the skeletal framework, thereby imparting high physicochemical stability to the resultant POP. 37,52–57 Moreover, this synthetic strategy (to obtain the iodine adsorbent – TP_POP-7 ) would be economical relative to the previously reported POPs for iodine capture that were obtained by employing transition metal-catalyzed cross coupling reactions. 58–61 After successful synthesis, TP_POP-7 was characterized using various analytical techniques.…”
