The single molecular tuning of charge balance has been demonstrated here by integrating a p-type dendron, an n-type dendron and a blue emissive Ir core into one dendritic platform. Compared with the commonly used physical blending, not only can the charge

A highly efficient base-, metal-, and oxidant-free catalytic O-H insertion reaction of diazoalkanes and phosphinic acids in the presence of B(C6F5)3has been developed. This powerful methodology provides a green approach towards the synthesis of a broad spectrum of α-phosphoryloxy carbonyl compounds with good to excellent yields (up to 99% yield). The protocol features the advantages of operational simplicity, high atom economy, practicality, easy scalability and environmental friendliness.

Paragraph 0079-0081, (2020/08/09)
The invention discloses a diamine monomer and a preparation method thereof, and polyimide and a preparation method and application thereof. Based on a light-emitting structural unit, a novel thermallyactivated delayed fluorescence (TADF) polyimide polymer material is prepared by adopting a polymer room-temperature polycondensation synthesis method, and the polyimide has excellent solubility, highglass-transition temperature and high thermal stability. Furthermore, an organic light-emitting device with excellent device performance is prepared by taking the polymer as a light-emitting layer through a simple solution spin-coating mode. The methods provided by the invention have the main characteristics of extremely high step economy and atom economy, simple experimental method operation, low design difficulty, diverse combination modes and good reaction region selectivity.

A mild, reagent-cyanide-free, and efficient synthesis of O-phosphinoyl-protected cyanohydrins from readily available α-substituted malononitriles was realized using diarylphosphine oxides in the presence of O2. Mechanistic studies indicated that in addition to the initial aerobic oxidation of the malononitrile derivative notable features of this process include the formation of a tetrahedral intermediate and a subsequent intramolecular rearrangement. The phosphinoyl-protecting group can be removed by alcoholysis or by reduction with DIBAL-H.
