Disclosed is a coordination polymer crystal with porous metal-organic frameworks (MOFs), in which, while a crystal state of the coordination polymer crystal is maintained, an additional material selected from the group consisting of an organic compound, a metal cluster, and an organometallic compound is chemically bonded to the coordination polymer crystal. Therefore it is possible easily adsorb and store more guest molecules regardless of a change in an ambient temperature or pressure due to the chemically bonded additional material.

An Ir compound can be a blue phosphorescent material. An organic electroluminescent device can use such a material. An organic layer, such as a light emitting layer, can be composed of the Ir compound. An organic electroluminescent device including such an organic layer may exhibit high color purity and emits dark blue light. Such an organic electroluminescent device may have low consumption power.
