where X.sub.1-X.sub.4, L.sub.1-L.sub.4 R.sub.1-R.sub.6 and Ar.sub.1-Ar.sub.8 are as defined in the specification. An organic light-emitting device includes the condensed cyclic compound.

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.

Anthracene derivatives each having a structure including an anthracene skeleton, a phenanthrene skeleton selected from among various phenanthrene skeletons different in bonding site which is bonded to the 9-position of the anthracene skeleton and a group selected from among various aryl groups and so on which is bonded to the 10-position of the anthracene skeleton. Organic EL devices made by using the derivatives exhibit high light emission efficiency and a long life.
