Abstract
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 NMR1H, 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.
