要旨

Herein, we report the synthesis of a novel metal–organic framework (MOF) photocatalyst via the postsynthetic pillaring method. The crystal transformation of photoactive 2D MOF to microporous 3D MOF was achieved, and the resultant MOF exhibited enhanced amine adsorption due to intrapore host–guest interaction. The oxidation of amine by the MOF was then utilized smartly to trigger perfluoroalkylation that can hardly be achieved by a MOF photocatalyst. The photocatalytic reaction exhibited excellent yield, high efficiency, and general applicability in the preparation of fluorine-containing functional chemicals. Mechanism studies show that the reaction was triggered by the photoinduced oxidation of amine by the MOF, which generated aminoalkyl radicals that are conducive to substrate activation. This study presents a goal-directed synthesis of a porous photocatalyst via the postsynthetic transformation of MOFs and provides a promising protocol based on host–guest interaction to achieve highly efficient photocatalysis.

Journal of Materials Chemistry A, B & C cover high quality studies across all fields of materials chemistry. The journals focus on those theoretical or experimental studies that report new understanding, applications, properties and synthesis of materials. The journals have a strong history of publishing quality reports of interest to interdisciplinary communities and providing an efficient and rigorous service through peer review and publication. The journals are led by an international team of Editors-in-Chief and Associate Editors who are all active researchers in their fields. Journal of Materials Chemistry A, B & C are separated by the intended application of the material studied. Broadly, applications in energy and sustainability are of interest to Journal of Materials Chemistry A, applications in biology and medicine are of interest to Journal of Materials Chemistry B, and applications in optical, magnetic and electronic devices are of interest to Journal of Materials Chemistry C. More than one Journal of Materials Chemistry journal may be suitable for certain fields and researchers are encouraged to submit their paper to the journal that they feel best fits for their particular article. Example topic areas within the scope of Journal of Materials Chemistry A are listed below. This list is neither exhaustive nor exclusive. Artificial photosynthesis Batteries Carbon dioxide conversion Catalysis Fuel cells Gas capture/separation/storage Green/sustainable materials Hydrogen generation Hydrogen storage Photocatalysis Photovoltaics Self-cleaning materials Self-healing materials Sensors Supercapacitors Thermoelectrics Water splitting Water treatment
