The present invention provides an arylamine compound having a molecular weight of from 1500 to 6000 represented by the general formula :According to the present invention, there can be provided an arylamine compound having excellent hole injection and transporting characteristics and being capable of forming a stable thin film. The system and method preserve the timing during redundant via insertion, which utilizes incremental timing and extraction updates. The thermostat is further capable of discontinuing operation of one or more systems for a minimum predetermined time period during following a request for a load curtailment period. Fasteners on each panel enable more complex, multi-panel messages to be formed as needed. The device also includes a comparator device operably connected to the storage device and configured to compare the first copy and the unique data for identity.
