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.

The present disclosure relates to an organic compound having the following structure, and an organic light emitting diode (OLED) and an organic light emitting device including the organic compound. Applying the organic compound into an emissive layer makes the OLED and the organic light emitting device lower their driving voltage, improves their luminous efficiency and color purity.

Ring A is a polycyclic aromatic hydrocarbon ring having a fluoranthene skeleton and having 16 to 60 carbon atoms and optionally has, as a substituent, a substituted or unsubstituted alkyl group or the like. Rings B.sub.1 and B.sub.2 are aromatic hydrocarbon rings having 6 to 18 carbon atoms and each have two or more electron withdrawing groups. Q.sub.1 and Q.sub.2 respectively represent one of the electron withdrawing groups of the ring B.sub.1 and one of the electron withdrawing groups of the ring B.sub.2, and are respectively located at an ortho position of the ring B.sub.1 and at an ortho position of the ring B.sub.2 with respect to the ring A.

A three step synthesis of the 8,12-dihydro-4H-dibenzo[cd,mn]pyren-3a.sup.2-ylium cation (triangulenium cation) is effected by cascade cyclization of a tetra-benzyl alcohol precursor in triflic acid solution. This cation is easily observed by NMR and optical spectroscopy. Quenching of the cation into basic solutions or by hydride transfer from triethylsilane provides access to stable dihydro and tetrahydro[3]triangulenes. This route makes several [3]triangulene precursors more readily available for development of new applications in the field of molecular electronics.
