In the present study, a systematic investigation of photoexcited fluorine supersensitization is carried out using in situ nuclear magnetic resonance (NMR) technique in combination with a newly designed photoresponsive device, and the validity of the photoresponsive device is confirmed. The reaction device consists of a light source, a light path, a coaxial collimating connector, and a solution mixing system, and the combination of nine fluorinated aromatic compounds with six photosensitizers is tested by the standard signal-to-noise (S/N) formula. In addition, the device's suitability is further verified by continuously monitoring the photopromoted open-loop reaction. The results show that the photoreactor can be well adapted to the commercially available NMR spectrometer for photochemical reaction detection and research.
