A rare-earth complex including a rare-earth ion, and a ligand coordinate-bonded to the rare-earth ion and having a condensed polycyclic aromatic group. The condensed polycyclic aromatic group is a residue formed by removing a hydrogen atom bonded to a condensed aromatic ring from a condensed polycyclic aromatic compound represented by the following Formula (I). In Formula (I), Rand Rrepresent hydrogen atoms or groups which are bonded to each other to form one aromatic ring or a condensed aromatic ring including two or more aromatic rings.

A rare earth complex including a rare earth ion and a ligand coordinated with the rare earth ion and having a condensed polycyclic aromatic group. The condensed polycyclic aromatic group is a residue formed by removing a hydrogen atom from a condensed polycyclic aromatic compound represented by the following formula (I) or (II): 

Rare earth complex and light emitting element

Disclosed is a rare-earth complex polymer including trivalent rare-earth ions and a phosphine oxide bidentate ligand represented by the formula (1). One phosphine oxide bidentate ligand is coordinated to the two rare-earth ions, and crosslinks the same. 

Rare-earth complex polymer

Provided is an organic ligand capable of providing a complex that has a three-dimensional network structure due to rare-earth element ions. Also provided is a coordination polymer which includes this organic ligand, has a new function, and contains rare-earth element ions. Additionally, a process for producing the coordination polymer and a use of the coordination polymer are provided. In particular, provided is a coordination polymer having repeating units of formula (10): wherein each of the variable groups is as defined in the specification.
