PURPOSE: A block copolymer is provided to offer a manufacturing method by which a white light emitting diode is manufactured more stable and easier than the existing way, without instability of colors according to a color ratio unlike the existing copolymerization. CONSTITUTION: A block copolymer is manufactured by the RAFT(reversible addition fragmentation chain transfer) polymerization of: one blue light emitting material selected from a poly(N-vinylcarbazole), polyfluorene, PCPP, and polyparaphenylene; and one yellow light emitting material selected from a poly(3-hexylthiophene), MEH-PPV, benzoic thiadiazole, and fluorenone. The block copolymer is used as a white luminescent material of the organic light emitting diode. |
