QUINOLINE COMPOUNDS SHOWING EXCITED-STATE INTRAMOLECULAR PROTON TRANSFER(ESIPT)

摘要

PURPOSE: Quinoline compounds showing excited-state intramolecular proton transfer(ESIPT) are provided. The compounds show various colors in electroluminescence as insertion of a functional group into a quinoline structure, improve the luminescence efficient and increase the luminescence period. CONSTITUTION: A quinoline monomer represented by the formula(2) is provided, wherein X is -OH or -OCH3. A quinoline dendrimer represented by the formula(3a) is provided, wherein X is selected from a compound of the formulas(3b to 3d); and Y is -H or a compound of the formula(3b). A quinoline polymer represented by the formula(4) is provided, wherein X and Y are independently -H or -OH. A method for producing the quinoline monomer of the formula(2) comprises the steps of: mixing metacresol and P2O5; and adding bisaminoketone and 2-hydroxy-4-methoxyacetophenone.
