Abstract: PURPOSE: A method for preparing luminescent polymer for the application to manufacture of light emitting diode(LED) is provided, in which one monomer having fluorine-substituted phenyl groups is reacted with dialdehyde monomer such as carbazole, phenyl, fluorene and thiophene. The luminescent polymer that is prepared by this method has superior electroluminescent efficiency to conventional luminescent polymers using p-conjugated polymers since its combination between electron and hole is well balanced. CONSTITUTION: The monomer having fluorine-substituted phenyl groups is selected from 2,3,5,6-tetrafluoro-1,4-xylene bis(triphenyl phosphonium bromide) benzene (formula 1) or 2,3,5,6-tetrafluoro-1,4-xylene bis(diethoxy phosphonate) benzene (formula 2). Such monomers react with dialdehyde monomer such as carbazole, phenyl, fluorene and thiophene, wherein two phosphonium salt or phosphonate are bonded with two aldehyde groups so that these are conjugated (π-conjugation).
