A series of 2,4-disubstituted quinolines were easily prepared through a one-pot reaction of structurally diverse 2-aminoaryl ketones with various arylacetylenes in the presence of K5CoW12O40Ë3H2O as a reusable and environmentally benign catalyst under microwave irradiation and solvent-free conditions.

as a Lewis acid. Subsequently, the synthesis of new aminoquinoline derivatives with good yields was performed using Pd/C and hydrazine. The photophysical investigations of quinoline derivatives show the substituent effect on the optical propertiescharacterization was done by absorption and photoluminescence measurements with quantum yields of up to 83 %, the presence of the aminogroup at position
