ABSTRACT:
Compounds, compositions, organic electronic devices, and methods for preparing organic electronic devices are described. The compounds of the invention contain at least two carbon-carbon triple bonds and a heteroaromatic ring having at least one —C═N— unit. The compounds can be used as electron transport agents in organic electronic devices such as organic electroluminescent devices.
