A facile protocol for the synthesis of phenoxazines and benzopyridoxazines by Smiles rearrangement have been demonstrated in short reaction time under microwave irradiation. The control experiments suggest that a reaction proceeds through Smiles rearrangement followed SNAr ring closure by in situ cascade process. In our present work, both the electron donating and electron withdrawing groups were tolerant and provided a corresponding phenoxazine/benzopyridoxazine in good to moderate yields.

Flexible chain structure-containing host material and organic light-emitting device
-
Paragraph 0044-0046, (2017/09/01)
The invention provides a flexible chain structure-containing host material and an organic light-emitting device, belonging to the technical field of organic optoelectronic materials and solving the technical problem in the prior art that the organic optoelectronic materials have poor luminescent properties such as low luminous efficiency. The flexible chain structure-containing host material has the beneficial effects that electron withdrawing groups and electron-donating groups are connected by flexible chains to break conjugate connection between the electron withdrawing groups and the electron-donating groups, thereby substantially improving triplet state energy level; and the organic light-emitting device prepared by using the flexible chain structure-containing host material has a good luminescent property, the luminous efficiency of up to 10.8cd/A and the driving voltage of up 3.1V and is an excellent OLED (Organic Light Emitting Diode) material.
