摘要： Disclosed is a composition including an anthracene derivative and a solvent and a method for fabricating a light-emitting element using the composition. The anthracene derivative has a diphenylanthracene moiety and a carbazole moiety linked to one of the phenyl groups of the diphenylanthracene moiety. The use of the composition enables the formation of a light-emitting element by a wet type method such as an ink-jet method, a spin coating method, and a dip coating method.

摘要： The present invention provides an evaluation method for evaluating whether a light-emitting element material to be evaluated is suitable for a host material or a guest material. By carrying out a first step of measuring absorption intensity of a light-emitting element material and a second step of irradiating the light-emitting element material with light for a predetermined period of time, repeatedly; thereby a change in absorption intensity with time is evaluated so that whether the light-emitting material is suitable for a host material or a guest material can be distinguished. The light emitted to the light-emitting element material preferably has a wavelength component which is absorbed by a skeleton which contributes to excitation of the light-emitting element material.
