Porous organic polymers for light-driven organic transformations

Abstract

Porous organic polymers (POPs), with their high specific surface area, low density, good stability, uniform pore size, structural versatility, and designability, have recently emerged as a powerful platform of heterogeneous photocatalysis.

Developing highly reducing conjugated porous polymer: a metal-free and recyclable approach with superior performance for pinacol C–C coupling under visible light

“…1 Among them, porous organic polymers (POPs) outperform the commonly-used transition metal complexes because of their unique advantages including excellent stability, being metal-free, cost effectiveness, recyclability, tunable photophysical properties through synthetic control and so on. 2 Despite the flourishing advancements, the majority are restricted to oxidative transformations such as oxidative hydroxylation of arylboronic acids, oxidation of sulfides, oxidative coupling of amines, and oxidative C–H functionalization reactions. 3 In sharp contrast, conjugated porous polymers that can efficiently drive challenging reductive reactions are rare.…”

A critical review on emerging photocatalysts for syngas generation via CO2 reduction under aqueous media: a sustainable paradigm

“…POPs are highlighted as competitive candidates in various applications. 190,201 Rationalizing POPs for photocatalytic CO 2 reduction to fuels/chemicals enlightens the development route for POPs as well as CO 2 reduced products. 193 This could be justified as structural modulation of POPs alters the CB-VB positions, and thus accordingly changes the generation of CO 2 reduced products.…”

“…Organic polymeric photocatalysts offer a unique and molecular-level structural layout of their optoelectronic and surface photocatalytic properties. 189–191 Over the period of time, organic polymers including carbon nitrides, 192 porous organic polymers, 193 covalent triazine frameworks 194 and covalent organic frameworks 195 have undergone an impressive development in their potential to propel photo catalytic CO 2 reduction to syngas. In comparison to inorganic photocatalysts, CO 2 reduction to syngas over organic photocatalysts is still in the infancy stage.…”

Extending the 2D conjugated microporous polymers linked by thiazolo[5,4-d]thiazole for green light-driven selective aerobic oxidation of amines

“…Counterintuitively, the structure-performance correlation of CMPs could be more easily established by the transformation of complex organic molecules. [34][35][36][37] To date, a range of CMPs have been designed to cater to various photocatalytic organic transformations. [38][39][40][41][42][43][44][45][46][47][48] However, the stratagem to precisely tune the optoelectronic properties of CMPs for improving their performance needs to be further explored.…”
