Carbazole- and thiophene-containing conjugated microporous polymers with different planarity for enhanced photocatalytic hydrogen evolution

Abstract

We report herein the synthesis of two carbazole-thiophene-based conjugated microporous polymers (Cz-3Th and Cz-4Th CMPs) with various degrees of planarity for photocatalytic hydrogen evolution from water. Interestingly, depending upon the...

Photocatalytic Water‐Splitting by Organic Conjugated Polymers: Opportunities and Challenges

“…The effect of planarity on the photocatalytic performance of carbazole-thiophene-based CMPs was studied. [153] Conjugated polymers with different planarity (Cz-3Th and Cz-4Th CMPs) (Scheme 14) were synthesized (Cz-3Th-51) and Cz-4Th CMPs-52), and their photocatalytic performance towards water splitting was compared. High photocatalytic performance was by low-branched polymer (Cz-3Th).…”

Linear multiple-thiophene-containing conjugated polymer photocatalysts with narrow band gaps for achieving ultrahigh photocatalytic hydrogen evolution activity under visible light

“…Compared with inorganic photocatalysts, organic polymer photocatalysts show unique advantages including diverse structures, high elemental abundance, low toxicity, numerous synthetic methodologies and tunable electronic properties. 8–10 Classic organic polymer photocatalysts are mainly linear conjugated polymers (LCPs), 11–15 graphitic carbon nitrides (g-C 3 N 4 ), 16–18 conjugated microporous polymers (CMPs), 19–23 covalent organic frameworks (COFs), 24–26 and covalent triazine-based frameworks (CTFs). 27–29…”

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

“…37 CMPs have distinct topological properties and functionalities, large surface areas, high chemical stabilities, and adjustable pores, and they can receive and transfer light energy through their delocalized backbones. [38][39][40][41][42] CMPs have emerging applications in heterogeneous catalysis, 43,44 biomedical sensors, 45 gas adsorption and storage, [46][47][48] sensing, 49 and light emitters. 50 In addition, because of their high photon activities and extended conjugation, CMPs are attractive materials for the sorption and photodegradation of organic dyes in aqueous solutions.…”
