Abstract: Organo-metallic complexes for opto-electronic and sensory devices and their use in such devices are provided. The organo-metallic complex (triplet emitter) consists of a metal center and chelate ligands. At least one of chelate ligands comprises an aromatic or fused aromatic ring(s). Each ligand is covalently substituted with at least one, preferably two charge transport groups (ctg). The metal center can be coordinated by a spectator ligand. Presence of two ctgs at each ligand is advantageous for applications in organic light emitting diodes (OLEDs). Charge transport units facilitate hole and/or electron transport to the molecular center and allow for efficient exciton formation directly on the complex. Presence of ctgs on each ligand provides good shielding with respect to interactions with the environment. Emission quenching is strongly reduced and materials with high emission quantum yields are obtained.

Abstract: An air purifier includes a cabinet, an electrically driven fan, a replaceable filter element, and an air quality sensor. A display provides a visual indication of the air quality condition. A microprocessor is programmed to control the speed of the fan automatically according to the air quality condition. The microprocessor also computes when the filter element must be changed by totalling the time of operation and its speed (which equals air quality) so that for example the filter element will be changed more often (used for less aggregate time) when the air purifier is operated in a poor quality environment.

Abstract: In an otherwise well-known electric pop-up toaster, an auxiliary power switch is provided and is arranged to be opened by a timer after each toasting cycle. This ensures, in contrast to the well-known toaster arrangements, that power is interrupted to heating elements even if a carriage supporting slices of toast fails to move up at the end of a toasting cycle.
