Paragraph 0127, (2021/02/20)
The invention provides a 2, 4, 7-trisubstituted fluorene compound and an electronic device thereof. According to the 2, 4, 7-trisubstituted fluorene compound disclosed by the invention, a fluorene rigid structure is introduced, so that the 2, 4, 7-trisubstituted fluorene compound is excellent in film-forming property and thermal stability, and can be used for preparing an organic light-emitting device, an organic field effect transistor and an organic solar cell. In addition, the 2, 4, 7-trisubstituted fluorene compound can be used as a constituent material of a hole injection layer, a hole transport layer, a light emitting layer, an electron blocking layer, a hole blocking layer or an electron transport layer, and can reduce driving voltage, improve efficiency and brightness, prolong theservice life and the like. The preparation method of the 2, 4, 7-trisubstituted fluorene compound is simple, raw materials are easy to obtain, and industrial development requirements can be met.
Vitamin Catalysis: Direct, Photocatalytic Synthesis of Benzocoumarins via (-)-Riboflavin-Mediated Electron Transfer

supporting information, p. 1316 - 1319 (2018/03/09)
An operationally simple protocol is disclosed to facilitate entry to benzo-3,4-coumarins directly from biaryl carboxylic acids without the need for substrate prefunctionalization. Complementary to classic lactonization strategies, this disconnection relies on the oxidation competence of photoactivated (-)-riboflavin (vitamin B2) to generate the heterocyclic core via photoinduced single electron transfer. Collectively, the inexpensive nature of the catalyst, ease of execution, and absence of external metal additives are a convincing endorsement for the incorporation of simple vitamins in contemporary catalysis.
