Composite Material, Light-Emitting Element, Light-Emitting Device, Electronic Device, and Lighting Device

Abstract

A composite material including an organic compound and an inorganic compound and having a high carrier-transport property is provided. A composite material having a high carrier-injection property to an organic compound is provided. A composite material in which light absorption due to charge transfer interaction is unlikely to occur is provided. A light-emitting element having high emission efficiency is provided by including the composite material. A light-emitting element having a low drive voltage is provided. A light-emitting element having a long lifetime is provided. A composite material including a heterocyclic compound having a dibenzothiophene skeleton or a dibenzofuran skeleton and an inorganic compound exhibiting an electron-accepting property with respect to the heterocyclic compound is provided.

1 . A composite material comprising:
 a heterocyclic compound comprising one of a dibenzothiophene skeleton and a dibenzofuran skeleton; and   an inorganic compound exhibiting an electron-accepting property with respect to the heterocyclic compound.
