The invention relates to specific phenanthrenes, the use of the compound in an electronic device, and an electronic device containing at least one of said compounds. The invention further relates to a method for producing the compound and a formulation and composition containing one or more of the compounds.

The present invention relates to a method for prevention of premature polymerization during the preparation, purification, transportation and storage of a polymerizable compound with at least one conjugated unsaturated group in the presence of an azine dye-based compound as inhibitor. Further the present invention relates to methods of preparing such inhibitors as well as to the inhibitors itself, as well as to methods of improving solubility and stability of dissolved inhibitors.

Methods, systems, and apparatus for monitoring and controlling electronic devices through the use of wired and wireless protocols. The systems and apparatuses may monitor their environment for signals from electronic devices. They may then take and disambiguate the signals that are received from the devices in their environment in order to identify said devices and associate control signals with them. The systems and apparatuses may then use communication means to send control signals to the identified electronic devices. Input and output transmission means for the systems and apparatuses may include, but are not limited to, powerline communication, Wi-Fi, Bluetooth, ZigBee, and 6LoWPAN. Signal processing and device identification may be done onboard the device, or may be done at a remote location. Multiple apparatuses or systems may be connected together into networks, including mesh networks, in order to make for a more robust architecture.

An organic light-emitting device comprises an anode, a cathode and a light-emitting layer between the anode and the cathode. The light-emitting layer comprises a compound of formula (I): ##STR00001## wherein Ar.sup.1, Ar.sup.2, Ar.sup.3, Ar.sup.6 and Ar.sup.7 in each occurrence independently represent an unsubstituted or substituted aryl or heteroaryl group; X independently in each occurrence represents S or O; R independently in each occurrence represents H or a substituent; p is 0 or 1; q is 0 or 1; f is 1, 2 or 3; g is 1, 2 or 3; and adjacent groups Ar.sup.3 or adjacent groups Ar.sup.2 may be linked by a divalent group to form a ring. This compound can provide a bluer emitter that can be blended into current host formulations (deep blue, CIEy<0.08) suitable for solution processing.
