摘要 |
A novel organic material with fewer impurities, a light-emitting element including the organic material, and a light-emitting device, an electronic appliance, and a lighting device each of which includes the light-emitting element are provided. The organic material is obtained by coupling an aryl halide and an aryl boronic acid or an aryl boronic acid ester. The aryl boronic acid or the aryl boronic acid ester includes at least one of a first impurity in which a boryl group of the aryl boronic acid or the aryl boronic acid ester is substituted by hydrogen and a second impurity in which a molecular mass of 16 or 17 is added to the molecular mass of the first impurity. The concentration of an impurity other than the first impurity and the second impurity is 1% or lower. |
