摘要：
The invention relates to a light-emitting material having high emitting efficiency, high luminance and durability for use in an organic light-emitting device and to an organic electroluminescent (EL) device, in which the light-emitting material is used. The light-emitting material contains a light-emitting substance which is spatially constricted and confined in an order of two dimensions or more, thus providing a high efficient organic light-emitting device based on emission of phosphorescence from an excited triplet state.
