摘要

Disclosed is a solution containing an organic EL material, which comprises an organic EL material and a solvent. The organic EL material comprises a host and a dopant. The host has an organic EL functioning moiety A which comprises a low-molecular organic EL material and a solubilizing moiety B which can bind to the organic EL functioning moiety A to cause the low-molecular organic EL material to be dissolved in the solvent and is represented by the formula: A-B-E [wherein E represents a terminal group]. A is a low-molecular organic EL material having an anthracene backbone. B is formed by the bonding of a moiety represented by the formula (3) to a moiety represented by the formula (4). In the formula (3), the bond is contained at ortho-position or meta-position in the unit. In the formula (4), the bond is contained at para-position in the unit. When the number of the moieties represented by the formula (3) is expressed by a and the number of the moieties represented by the formula (4) is expressed by b, a and b satisfy the following formula: 3 = a+b = 20 and a = b.
