Document Type and Number:
Japanese Patent JP2023135667
Kind Code:
A
Abstract:
To provide a purification liquid composition and a purification method capable of effectively conducting a process for purifying a conductive organic material used for an organic light-emitting element at high purity at an ordinary temperature.SOLUTION: An organic material purification composition contains an ionic liquid in which a positive ion and a negative ion are bound, and an organic solvent. The organic solvent is alcohol or ketone. Weight of the alcohol is 1.0 time to 5.0 times to weight of the ionic liquid. By mixing an organic material which is a target for purification with the organic material purification composition with low viscosity at an ordinary temperature and stirring them, then conducting washing and drying after separating an organic material by filtration, mixed organic material is purified.SELECTED DRAWING: Figure 3
