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,in-line-formulae description="In-line Formulae" end="lead"?X1—Ar1—X2 (1)in-line-formulae description="In-line Formulae" end="tail"?wherein, Ar1represents 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 X1and X2represent leaving groups. By using the polymeric fluorescent substance, a high performance polymer LED can easily be obtained.
