The azepine compound capable of emitting a light by light-irradiation or action of an electric field is represented by the following formula (I) or (II):
1
wherein X
1
and X
2
are the same or different, each representing an electron attractive group; R
1
represents a hydrogen atom, an alkyl group, an aryl group, an aralkyl group, or an alkoxy group; R
2
represents an amino group or an N-substituted amino group, or, in the formula (I), R
2
bonds a carbon atom adjacent to a ring Z to form a ring; and the ring Z represents a hydrocarbon ring which may have a substituent or a heterocycle which may have a substituent.
The compound is useful as a functional material, thus, an organic electroluminescence device can be obtained by interposing an organic layer composed of the above compound between a pair of electrodes.
具有通过光照射或电场作用而发出光的氮杂环化合物的化学式如下(I)或(II):1其中,X1和X2相同或不同,分别表示电子吸引基团;R1表示氢原子、烷基、芳基、芳基烷基或烷氧基;R2表示氨基或N-取代氨基,或在式(I)中,R2与环Z相邻的碳原子连接以形成环;环Z表示可能具有取代基的碳氢环或可能具有取代基的杂环。该化合物可用作功能材料,因此,在一对电极之间插入由上述化合物组成的有机层可获得有机电致发光器件。
