Mono/double-anchored phenothiazine-based dyes (DCE1-DCE4) containing various N-substituents (12-crown-4-substituted phenyl, 4-hexoxyphenyl, and bare phenyl) were synthesized and applied as sensitizers for dye-sensitized solar cells (DSSCs). The incorporat
Photoredox Catalytic Activation of Sulfur Hexafluoride for Pentafluorosulfanylation of α-Methyl- and α-Phenyl Styrene

Sulfur hexafluoride is inert, non-toxic, and cannot simply be applied as pentafluorosulfanylation reagent. We present the first photoredox catalytic way to convert it into pentafluorosulfanylated α-methyl and α-phenyl styrenes simply by using light. The work tackles the challenges of precise activation of sulfur hexafluoride by a photoredox catalyst with designed consecutive electron transfer cycles in a fashion that styrenes trap the generated pentafluorosulfanyl radical. The method overcomes the highly problematic access to vinylic and allylic pentafluorosulfanyl styrenes and combines it with the disposal of the most potent greenhouse gas. Together with the use of light as energy source, an exceptionally high level of sustainability is gained.
Photoredox Catalytic α-Alkoxypentafluorosulfanylation of α-Methyl- and α-Phenylstyrene Using SF6

SF6 was applied as pentafluorosulfanylation reagent to prepare ethers with a vicinal SF5 substituent through a one-step method involving photoredox catalysis. This method shows a broad substrate scope with respect to applicable alcoh

We describe a photocatalytic system that reveals latent photooxidant behavior from one of the most reducing conventional photoredox catalysts, N-phenylphenothiazine (PTH). This aerobic photochemical reaction engages difficult to oxidize feedstocks, such as benzene, in C(sp2)-N coupling reactions through direct oxidation. Mechanistic studies are consistent with activation of PTH via photooxidation and with Lewis acid cocatalysts scavenging inhibitors inextricably formed in this process.

Organic room-temperature phosphorescent material as well as preparation method and application thereof

Paragraph 0074-0080, (2021/02/06)
The invention discloses an organic room-temperature phosphorescent material as well as a preparation method and application thereof. The structure of the phosphorescent material is shown as a formula(I), a formula (II) or a formula (III). The molecules all contain one or more phenothiazine units, and when the molecules are dispersed and immobilized in a rigid matrix PMMA, the material doped withthe molecules can be induced to generate room-temperature phosphorescence under the excitation of an ultraviolet lamp. Phenothiazine derivative molecules promote oxygen molecules in a matrix materialto be converted into singlet oxygen in the light induction process, and after the oxygen molecules are greatly consumed, the phenothiazine derivative molecules emit phosphorescence due to the fact that non-radiative energy dissipation is inhibited by a rigid environment provided by the matrix. The activated material can be inactivated again by heating or standing for a long time, and the process can be carried out repeatedly. The molecules in the invention can realize light-induced information writing and erasing in a transparent polymer matrix material, material support is provided for organic light information storage, reading and writing, and the practicability is extremely high.
