摘要 |
An organic electroluminescent material-containing solution contains an organic electroluminescent material and a solvent. The organic electroluminescent material contains a host and a dopant the host contains an organic electroluminescence-functional portion A formed of a low-molecular organic electroluminescent material and a soluble portion B bonded to the organic electroluminescence-functional portion A for solubilizing the low-molecular organic electroluminescent material in the solvent, the host being represented by a formula of A-B-E (where E represents a terminal group). The portion A is a low-molecular organic electroluminescent material having a central anthracene skeleton. The portion B is formed by bonding structures represented by the following formula (3) with structure(s) represented by the following formula (4). Units represented by the formula (3) include bonds in ortho positions or meta positions while unit(s) represented by the formula (4) includes bonds in para positions. When (a) represents the number of the structures represented by the formula (3) while (b) represents the number of the structure(s) represented by the formula (4), the number (a) and the number (b) satisfies both relationships respectively represented by 3<=(a)+(b)<=20 and (a)<=(b).
