Solution-processed thermally stable amorphous films of small molecular hole injection/transport bi-functional materials and their application in high efficiency OLEDs
摘要:
使用TPD(BTPA)作为空穴传输材料的OLED,在高电流下表现出色,其最高CEmax达到了5.83 cd A-1,相比于具有相同结构的小分子HTMs(Mw < 6000),这是由于其出色的热稳定性。

The present invention discloses processes for producing γ-nitrocarbonyl and γ-dicarbonyl compounds, which can be precursors in the synthesis of pyrrole compounds. A process for producing pyrroles such as 2,5-dimethylpyrrole, and structurally similar pyrrole compounds, is also disclosed.
The Lossenrearrangement is a classic process for transforming activated hydroxamic acids into isocyanate under basic or thermal conditions. In the current report we disclosed a consecutive Lossenrearrangement/transamidation reaction in which unactivated hydroxamic acids were converted into N-substituted formamides in a one-pot manner under catalyst- and additive-free conditions. One feature of this

A photoinduced oxidative formylation of N,N-dimethylanilines with molecularoxygen in the absence of an external photocatalyst was developed and provided the corresponding formamides in good yields under mild reaction conditions. Investigations indicated that both the starting material and product act as photosensitizers and that 1O2 coexists with O2•– during the reaction through energy transfer and
在没有外部光催化剂的情况下,开发了N,N-二甲基苯胺与分子氧的光诱导氧化甲酰化反应,并在温和的反应条件下以良好的收率提供了相应的甲酰胺。研究表明,原料和产物均充当光敏剂,并且在通过能量转移和单电子转移过程的反应过程中,1 O 2与O 2 •–共存。
