MATERIAL FOR CHARGE-TRANSFERRING THIN FILM, AND CHARGE-TRANSFERRING THIN FILM

摘要

The present invention addresses the problem of providing a material for long-life charge-transferring thin films and a charge-transferring thin film. The material for charge-transferring thin films according to the present invention comprises an aromatic compound, and is characterized in that the aromatic compound has at least two aromatic hydrocarbon rings or aromatic heterocycles that have highest occupied molecular orbitals and lowest unoccupied molecular orbitals which are drawn by a molecular orbital calculation and are distributed on the aromatic compound and which are spatially separated from each other, that the aromatic compound has a C_3-20 alkyl group, and that a single layer comprising the aromatic compound gives a current-excitation emission spectrum satisfying the following relationship (1). Relationship (1): a/b1
