This disclosure relates to chrysene compounds with deep blue emission that are useful in electroluminescent applications. It also relates to electronic devices in which the active layer includes such a chrysene compound.
This invention relates to chrysene compounds having green emission, that are useful in electroluminescent applications. It also relates to electronic devices in which the active layer includes such a chrysene compound.
A chemo- and stereoselective Pd-catalysed semi-reduction of alkynes to (Z)-alkenes has been performed in a phosphonium-based DES by using the in situ generation of H2 from Al/H2O. The antitumor agent combretastatin A4 has been also synthesized.
通过利用 Al/H2O 原位生成 H2,在膦基 DES 中进行了炔烃到 (Z)- 烯的化学和立体选择性钯催化半还原反应。此外,还合成了抗肿瘤药物考布他丁 A4。
