Xu, Hui; Li, Xia; Hao, Huimin; Dong, Xiaoyun; Sheng, Wenlong; Lang, Xianjun published the artcile< Designing fluorene-based conjugated microporous polymers for blue light-driven photocatalytic selective oxidation of amines with oxygen>, Application In Synthesis of 3959-07-7, the main research area is microporous conjugated polyfluorene polycarbazole blue light photocatalytic amine oxidation.
Conjugated microporous polymers (CMPs) have been showcased with a brilliant prospect in organic semiconductor photocatalysis, attributing to accessible mol. design, chem. stability and environmental friendliness. Here, two novel fluorene-based CMPs were designed and conveniently synthesized with carbazole as an electron donor. Importantly, subtle variation of substituent at the methylene bridge (9-position) of fluorene precursor results in different performances in which di-Me substituent was proven to be more efficient than difluoro substituent for blue light photocatalysis. MFC [9,9′-(9,9-dimethyl-9H-fluorene-2,7-diyl)bis(9H-carbazole)]-CMP has a much larger sp. surface area, a more favorable redox position, and resultantly a superior photocatalytic performance during blue light-driven selective oxidation of amines into imines with oxygen (O2) in an environmentally benign solvent ethanol (C2H5OH). This work suggests that subtle tweaking in electron acceptors could give rise to superior photocatalytic activity for CMPs in selective chem. conversions.
