POLYMER HAVING LUMINOUS UNIT EMITTING LIGHT AFTER CHANGE IN CHEMICAL STRUCTURE AND ORGANIC ELECTROLUMINESCENT ELEMENT USING THE SAME

摘要

PROBLEM TO BE SOLVED: To obtain a polymer that inexpensively and safely emits a light in a wide visible light range from a short-wavelength (blue) to a long-wavelength (red) and to provide a light emitting apparatus using the polymer, preferably an organic electroluminescent (EL) element. SOLUTION: The polymer has a luminous unit having a changing chemical structure in which a first luminous unit is changed to a second luminous unit having a chemical structure different from that of the first luminous unit to emit a light. The second luminous unit is preferably returned to the first luminous unit after the emission. COPYRIGHT: (C)2006,JPO&NCIPI
