Description
Summary:A method for the preparation of 2-morpholinocinchomeronic acid dinitrile derivatives (2-morpholinopyridine-3,4-dicarbonitriles) was developed. The optical properties of the obtained products were investigated both in solution and the solid state. It was found that the synthesized compounds exhibit fluorescence both in solution and in the solid state from the blue to green region of the spectrum, depending on the substituents at the fifth and sixth positions of the pyridine ring. It was found that the relative quantum yield in benzene reaches 50%.
