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.
