report the first fully automated continuous‐flow platform for fluorescencequenching studies and Stern–Volmer analysis. All the components of the platform were automated and controlled by a self‐written Python script. A user‐friendly software allows even inexperienced operators to perform automated screening of novel quenchers or Stern–Volmer analysis, thus accelerating and facilitating both reaction

were designed and synthesized, allowing precise control of the photocatalytic reactivity for the controllable reduction of arylhalides via a metal-free process. The screened-out CCB (5CzBN), a metal-free, low-cost, scalable and sustainable photocatalyst with both strong oxidative and reductive ability, exhibits superior performance for both dehalogenation and C C bond-forming arylation reactions.
The present invention relates to an organic mixture and an application thereof in organic electronic devices. The organic mixture comprises a spirofluorene organic compound containing a fused heterocyclic ring and an aromatic fused heterocyclic organic compound containing an electron-donating group. A combination of the two materials may be used as a host material of a phosphorescent organic light-emitting diode (OLED), which may use the energy of excitons and balance the charge transport to the greatest extent and which may effectively reduce the concentration of excitons and the operating voltage of a corresponding device, thereby effectively improving the efficiency and service life of the related electronic device in order to provide an effective solution for improving the overall performance of an organic electronic device.

An organic compound having a naphtho fluoranthene core and a hetero aromatic group bonded to a specific position of the naphtho fluoranthene core, an organic light-emitting diode and an organic light-emitting device including the compound are disclosed. Since the organic compound has a narrow Stokes Shift between an absorption wavelength and an emission wavelength, the organic compound has a broad overlapped area between its absorption peak and an emission peak of a delayed fluorescent material, and therefore it can emit blue light with high color purity. It is possible to manufacture an organic light-emitting diode (OLED) and an organic light-emitting device that enhance luminous efficiency and color purity using the organic compound.
