Click-based conjugated microporous polymers as efficient heterogeneous photocatalysts for organic transformations

Abstract

Due to the tunable porous structure and photoelectric property, conjugated microporous polymers (CMPs) have provided a new platform for visible-light driven photocatalysis. Some synthetic methods like Sonogashira, Suzuki, oxidative coupling...

Covalent organic framework with sulfonic acid functional groups for visible light-driven CO2 reduction

“…19 Conjugated microporous polymers (CMPs) can capture light and have an effective charge separation capability, so they have been extensively studied in the eld of photocatalysis. [20][21][22] However, the formation of CMPs is controlled by kinetics, and they are linked by irreversible organic covalent bonds. Therefore, the structure is amorphous and forms a disordered microporous polymer.…”

Rationally designed conjugated microporous polymers for efficient photocatalytic chemical transformations of isocyanides

“…Some 1,2,3-triazole-containing CMPs have been prepared by our group and presented excellent photocatalytic activities in organic transformations. 30 On the other hand, owing to the high conjugated electron density and rigid structure of thiophene, thiophene-containing polymers have been extensively studied in the field of organic semiconductors over the past few decades. 31 Recently, thiophene has been used as an electron donor unit to tailor the photocatalytic activities of CMP photocatalysts.…”

“…Consequently, the development of metal-free heterogeneous photocatalysts with the advantages such as high activity and stability remains a challenge. Among the reported metal-free heterogeneous photocatalysts, conjugated microporous polymers (CMPs), 14–25 covalent-organic frameworks (COFs), 26–30 covalent triazine frameworks (CTFs), 31–36 and g-C 3 N 4 , 37–40 in which the chemically stable CMPs have received extensive attention due to their unique structural features to achieve efficient organic transformations. 41–43…”
