<p><P>PROBLEM TO BE SOLVED: To provide an electronic device which comprises an intermediate layer enabling smooth transfer of carriers between layers and has an excellent characteristic, and also reliable electronic equipment using the device. <P>SOLUTION: The electronic device comprises a pair of electrodes and a laminate 9 disposed therebetween. The laiminate 9 has a hole transfer layer (first organic semiconductor layer) 4, a luminous layer (second organic semiconductor layer) 6, and an intermediate layer 5 provided between the layers 4 and 6 to be contacted with the both layers. The intermediate layer 4 is made of a compound expressed by formula A<SP>1</SP>-B-A<SP>2</SP>as its main material. In the formula, A<SP>1</SP>and A<SP>2</SP>independently denote a group containing at least one of first to third class amino groups, a hydroxyl group, a carbonyl group, and a carboxyl group. Either one of A<SP>1</SP>and A<SP>2</SP>is only required. B denotes a group containing a fluorene ring. In the compound, the groups A<SP>1</SP>and A<SP>2</SP>are orientated toward the hole transfer layer 4, and the group B is orientated toward the luminous layer 6. <P>COPYRIGHT: (C)2007,JPO&INPIT</p> |
