Abstract
A novel organic compound is provided. An organic compound that emits light with high chromaticity is provided. An organic compound that emits blue light with high chromaticity is provided. An organic compound with high emission efficiency is provided. An organic compound having an excellent hole-transport property is provided. An organic compound having high reliability is provided. An organic compound that has a naphtho[2,3-b;7,6-b′]bisbenzofuran skeleton or a naphtho[2,3-b;7,6-b′]bisbenzothiophene skeleton and has a molecular weight of less than or equal to 5000 is provided. The present inventors have found that the organic compound is a significantly effective skeleton as a luminophor of a light-emitting element. The organic compound has high emission efficiency and exhibits favorable blue light emission; thus, a light-emitting element using the organic compound can be a blue light-emitting element with high emission efficiency.
