Recent Applications of Porous Organic Polymers Prepared via Friedel–Crafts Reaction under the Catalysis of AlCl₃: A Review

Abstract

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.

Novel nanoscale vanillin based covalent triazine framework as a novel carrier for sustained release of imatinib

“…The synthesis of CTFs was firstly reported through cyclotrimerization of aromatic nitrile and the first CTFs was introduced by Thomas et al in 2008 via trimerization of 1,4‐dicyanobenzene by ionothermal method 14,15 . Later CTFs were prepared in strong Brønsted acid conditions (CF 3 SO 3 H), also Schiff base and Friedel‐Crafts reaction 16 . Beyond their superior advantages in gas storage and catalysis, these porous crystalline structures have capable to act as potential drug carriers.…”

In this electron rich structures, the lone pair of electrons on the nitrogen could be capable to reversibly anchor the guest molecules resulted in convenient loading and also situational release.…”

Improving Photosensitivity and Transparency in Organic Phototransistor with Blending Insulating Polymers

“…Because small organic molecules and polymers can be easily processed in solution, organic electronics have the potential to be fabricated using low-cost, large-area, low-temperature-processing technology [ 21 , 22 ]. The properties of these materials can also improve the performance of electronic devices via rational material synthesis and molecular design, which can include the doping and/or mixing of materials [ 23 , 24 , 25 ].…”
