查询词典 emitting

We adopt a similar discotic liquid crystalline synthesis way to synthesize target molecules 7, 11, 15, 19, 21 in this article. The target molecules have a central triphenylene core and different side chains including triphenylamine derivatives and carbazole molecules. We observe these molecules optical and electrochemical properties and the effect of hole-transport layers in organic light emitting diode.
