Abstract
Provided is a method of producing a polymeric fluorescent substance wherein one or more monomers represented by the general formula (1) are polymerized in the presence of a zerovalent nickel complex, X1—Ar1—X2 (1) wherein, Ar1 represents a divalent group selected from the group consisting of arylene groups, divalent heterocyclic compound groups, and divalent or trivalent hetero atom-bonded arylene or divalent heterocyclic compound groups, and X1 and X2 represent leaving groups. By using the polymeric fluorescent substance, a high performance polymer LED can easily be obtained.

A method of producing a polymeric fluorescent substance wherein one or more monomers represented by the general formula (1) are polymerized in a solvent containing one or more aromatic hydrocarbon solvents and/or ether solvents in the presence of a zerovalent nickel complex in an amount of 1.8 mol or more based on 1 mol of said monomers,
- X1—Ar1—X2 (1)
- wherein, Ar1 represents a divalent group selected from the group consisting of arylene groups, divalent heterocyclic compound groups, and divalent or trivalent hetero atom-bonded arylene or divalent heterocyclic compound groups;
- Ar1 may have one or more substituents;
- X1 and X2 represent leaving groups which may be the same or different.
