Provided is an anthracene compound of Chemical Formula 1:

Anthracene compound and organic light-emitting device comprising same

A compound of Chemical Formula 1: and an organic light emitting device including the same.

Compound and organic light emitting device comprising same

An organic light emitting device including a first electrode; a second electrode provided opposite to the first electrode; and one or more organic material layers provided between the first electrode and the second electrode, wherein one or more of the one or more organic material layers include a compound of Chemical Formula 1 and a compound of Chemical Formula 2.

Organic light-emitting device

The present invention pertains to an air-circulating electric roaster designed to enhance the safety of cooking utensils by interrupting the drive power based on temperature changes in the grill plate and the positional detachment of the roaster. The invention comprises an outer bodyand an inner body, with an electrically heated operating heating lampprovided in the inner body. It further includes a heating unit, a grill plate, a bottom cap, a blower, temperature and pressure detection means, a platinum catalyst filterarranged externally on the inner body, a water level sensorpositioned inside the oil collector, and seismic vibration detection meansinstalled on the outer body. These components are integrated into an air-circulating electric roasterand a control boxdesigned to inform about the operational status of the electric roaster.

Air circulation electric roaster for a table with safety function

The present disclosure provides an organic light emitting device including a first electrode, a second electrode provided to face the first electrode, and an organic material layer including a light emitting layer provided between the first electrode and the second electrode, and the light emitting layer including a compound represented by Formula 1, a compound represented by Formula 2, and a compound represented by Formula 3.

An organic light emitting device including a compound of Chemical Formula 1 and a compound of Chemical Formula 2, wherein

Organic light emitting diode

An air circulation roaster for tables with a safety function enabled to remove foreign substances (oil and nitrogen dioxide) generated during cooking of meat, reducing contamination of the air around the roaster, has a safety function that cuts off power pending the sensed temperature of the roast plate. The air circulation roaster has a temperature sensor detecting the temperature of the roast plate, a control box placed outside the body when the temperature cuts off power supplied to the heating lamp when the heating unit exceeds the set limit. A platinum catalyst filter placed around the outside of the heating unit is coated with platinum on a network-shaped ceramic.

Table air circulation roaster with safety function

The present specification relates to a compound represented by the following Formula 1 and an organic light emitting device including the same. The compound is used as a material for an organic material layer of the organic light emitting device.

Organic compound and organic light-emitting device comprising same
