Embodiments provide a light-emitting device that includes a first electrode, a second electrode facing the first electrode, an interlayer between the first electrode and the second electrode and including an emission layer, and an amine-containing compound that is represented by Formula 1, which is explained in the specification:

##STR00001##

The present invention relates to compounds of the formula (1) which are suitable for use in electronic devices, in particular organic electroluminescent devices, and to electronic devices which comprise these compounds.

A method for reducing the mutagenicity of polycyclic aromatic compounds (PAC's) having one or more bay regions which involves alkylating the PAC's with an alkylating agent in the presence of a catalyst to lower the mutagenicity down to as much as about 0.1. The resulting alkylated polycyclic aromatic compounds retain their physical and chemical properties for safe industrial use including as rubber processing oils, inks, etc.

Methods, systems, and apparatus for monitoring and controlling electronic devices using wired and wireless protocols are disclosed. The systems and apparatus may monitor their environment for signals from electronic devices. The systems and apparatus may take and disambiguate the signals that are received from the devices in their environment to identify the devices and associate control signals with the devices. The systems and apparatus may use communication means to send control signals to the identified electronic devices. Multiple apparatuses or systems may be connected together into networks, including mesh networks, to make for a more robust architecture.

Disclosed herein are embodiments of polycyclic aromatic compounds and methods of making and using the same. Various different types of polycyclic ring systems are disclosed, including, but not limited to, polymeric aromatic compounds (e.g., nanographene compounds), pentacene-like compounds, chiral aromatic compounds, asymmetric arene compounds formed from naphthalene-, anthracene-, phenanthrene-, and pyrene-based starting compounds, and dimerized aromatic compounds. Also disclosed herein are novel benzannulation-based methods for making the disclosed polycyclic aromatic compounds.

The present disclosure relates to an organic electroluminescent compound and an organic electroluminescent device comprising the same. The organic electroluminescent device having improved driving voltage and/or current efficiency characteristics can be provided by comprising the organic electroluminescent compound according to the present disclosure.
