Facile metal-free synthesis of pyrrolo[3,2-b]pyrrolyl-based conjugated microporous polymers for high-performance photocatalytic degradation of organic pollutants

Abstract

Conjugated microporous polymers (CMPs) outperform other materials in a variety of ways due to their intrinsic topological features, high chemical stabilities, and tunable pores, and they can accept and transfer...

Donor to Acceptor Charge Transfer in Carbazole‐based Conjugated Microporous Polymers for Enhanced Visible‐Light‐Driven Photocatalytic Water Splitting

“…[35,36] Also, modifying their starting building blocks has been developed for use in wide spectrum of applications, including catalysis, energy storing, sensing, photo luminescence, light-harvesting, dye adsorption, and gas uptake. [37][38][39][40][41][42][43][44][45][46][47][48][49] In addition, owing to the good delocalization of π-electrons and suitable band gap of CMPs, they have been applied as photocatalytic semiconductors for different purposes, for example, amine and sulfide oxidation, hydrogen liberation, oxygen, and indole activation, and cycloaddition. [50][51][52][53][54][55][56] Meanwhile, a donor-acceptor (D-A) copolymer type has emerged as an eminent strategy for achieving excellent photocatalytic hydrogen generation efficiency.…”

“…Recently, many research studies focused on CMPs mainly because of their good porosities and surface areas, high physical and chemical stabilities, and superior optical properties [35,36] . Also, modifying their starting building blocks has been developed for use in wide spectrum of applications, including catalysis, energy storing, sensing, photo luminescence, light‐harvesting, dye adsorption, and gas uptake [37–49] . In addition, owing to the good delocalization of π‐electrons and suitable band gap of CMPs, they have been applied as photocatalytic semiconductors for different purposes, for example, amine and sulfide oxidation, hydrogen liberation, oxygen, and indole activation, and cycloaddition [50–56] …”

π-Electron-Extended Triazine-Based Covalent Organic Framework as Photocatalyst for Organic Pollution Degradation and H2 Production from Water

“…The physicochemical characteristics of light-absorbing polymers determine their capacity to both absorb light and carry out the photocatalytic reaction [ 15 , 62 , 63 ]. In addition, due to their modulated π-electron delocalization and density, triazine derivatives have a solid reputation as fluorescent materials [ 64 , 65 ].…”

“…Among them, sorption-based technologies received more attention due to their cost-effectiveness [ 9 , 10 ]. Amorphous porous materials, such as natural zeolites, fibers, and nanoscale-ordered porous materials, have been invented as dye adsorbents [ 11 , 12 , 13 , 14 , 15 , 16 , 17 , 18 ]. These porous sorbents, however, only adsorb contaminated dyes without degrading them, causing regeneration and secondary pollution issues [ 19 ].…”

“…It is believed that a 1,3,5-triazine unit correlated significantly with high photocatalytic efficacy in organic photocatalysts [ 60 ]. According to reports, extending the π-electron delocalization system of COFs significantly improved their electronic and optical attributes [ 15 ]. Along these lines, we developed π-electron extended triazine-based COF (TFP-TPTPh COF) through Schiff-base polycondensation of 1,3,5-triformylphloroglucinol (TFP-3OHCHO) with π-electron-extended 4′,4‴,4′′′′′-(1,3,5-triazine-2,4,6-triyl)tris(([1,1′-biphenyl]-4-amine)) (TPTPh-3NH 2 ) under solvothermal condition ( Scheme 1 ).…”
