标题:用于oled的高效纯有机室温磷光聚合物ppv衍生物
摘要:为了提高装置效率并降低成本,有必要开发具有室温磷光(rtp)的纯有机分子.设计并合成了一种高效的纯有机rtp聚合物聚对亚苯基亚乙烯基(ppv)衍生物(br-Ppv-Cho),它在496 Nm处具有蓝色发射,发射寿命为14.1μs,并且具有光致发光性.量子产率为12.2%,Homo和lumo分别为-5.35 Ev和-2.75 Ev,显示出在oled发射层中的巨大潜力.用ppv衍生物作为发光材料层制造的器件的最大亮度为194 Cd / M 2当br-Ppv-Cho的含量为0.5重量%时,显示出最佳的rtp性能.Br-Ppv-Cho的非常好性能来自于溴和芳香醛的取代基,Ppv衍生物的分子结构设计策略为有机rtp材料的设计和合成提供了有用的指导.

摘要:A process of preparing 6-O-alkyl erythromycin A is provided. The process includes the steps of protecting the oxime hydroxyl of 9-oxime erythromycin A with a benzoyl protecting group, protecting the 2'-hydroxyl group and optionally the 4'-hydroxyl group with an O-protecting group, alkylating the 6-hydroxyl, removing the benzoyl and O-protecting groups and deoximating the 9-oxime.

摘要:The present invention provides novel methods and processes for polymerizing unsaturated substrates, such as alkyne bearing monomers, with arenes. The polymerizations are catalyzed by gold (Au) catalysts/complexes and/or other cocatalysts. The invention further provides novel structurally complex polymers prepared in high yield via an intermolecular polyhydroarylation mechanism. Such resulting products comprise oligomeric and polymeric materials with novel molecular architectures and microstructures, which subsequently impart unique properties. The invention includes both the synthesis methods and processes and the resulting compounds and compositions of matter.
