Abstrakt: New highly fluorescent 2-imino-2H-pyrano[3,2-c]pyridin-5(6H)-onesderivatives were synthesized using a simple route. The present molecules were prepared by two methods with good yield. The structures were characterized by NMR 1 H, 13  C, and elemental analysis. Also, the effect of solvent and concentration on the fluorescence properties were demonstrated. However, the high fluorescence intensity in the range of 70,000-75,000 a. u. was obtained with a concentration equal to 10 - 6  M of prepared molecules. The intensity was influenced also by the molecule structure and solvent.
