本发明涉及有机发光化合物,其特征在于其为化合物,如下所示[化学式1],采用了根据本发明的有机发光化合物的有机电致发光器件,与传统的采用有机发光宿主材料的器件相比,具有更低的驱动电压,功耗效率优越,同时具有发光效率和寿命。 [化学式1]
An efficient synthesis of 9,10-disubstituted phenanthrenes is described in this Letter. These novel useful building blocks were obtained in a one-pot reaction including Suzuki–Miyaura cross-coupling followed by a Dieckmann–Thorpe ring closure under microwave irradiation. The selection of the appropriate reagents and the optimal reaction conditions to isolate the intermediate biphenyl compound or the
A one-pot synthesis of novel poly-substituted phenanthrenes is described in this article through a Suzuki-Miyaura cross-coupling followed by a Dieckmann-Thorpe ring closure under microwave irradiation. The selection of the appropriate starting materials allowed us to introduce diversity on various positions of the phenanthrene ring system. (C) 2010 Elsevier Ltd. All rights reserved.
