This invention relates to electroluminescent metal complexes of the formula electronic devices comprising the metal complexes and their use in electronic devices, especially organic light emitting diodes (OLEDs). The metal complexes of formula (I) show high emission efficiency, excellent vaporizability, thermal stability, processing stability, high charge carrier mobilities, low turn-on voltage and high temperature stability of the emission color.
Provided is a novel heterocyclic compound which has excellent heat resistance and can be used as a host material for a light-emitting substance (a substance emitting fluorescence or a substance emitting phosphorescence). A light-emitting element includes a heterocyclic compound which includes one dibenzo[f,h]quinoxaline ring, one ring having a hole-transport skeleton, and two to eight benzene rings. Note that in the above structure, the molecular weight of the heterocyclic compound is greater than or equal to 564 and less than or equal to 1000.
An object is to provide a novel heterocyclic compound which can be used for a light-emitting element, as a host material of a light-emitting layer in which a light-emitting substance is dispersed. Other objects are to provide a light-emitting element having low driving voltage, a light-emitting element having high current efficiency, and a light-emitting element having a long lifetime. Provided are a light-emitting element including a compound in which a dibenzo[f,h]quinoxaline ring and a hole-transport skeleton are bonded through an arylene group, and a light-emitting device, an electronic device, and a lighting device each using this light-emitting element. The heterocyclic compound represented by General Formula (G1) below is provided.
