The synthesized compounds were then characterized by using (HNMR)-H-1,(CNMR)-C-13, FTIR spectroscopies and elemental analyses. It was seen that the Schiff bases generated in the presence of OH group at ortho position of benzaldehyde derivatives. However, the products were naphtho[1,2-d]oxazoles in other cases. Then, the synthesized compounds were photophysically investigated by UV absorption and fluorescence emission spectroscopies. As a result, these Schiff bases have shown long wavelength absorption (lambda(max): 386 nm) and emission (lambda(max): 429-437 nm) effect while synthesized naphtho[1,2-d]oxazole derivatives have a set of absorption (lambda(max): about 296, 308, 320 nm) and emission maxima (lambda(max): 378-395 nm) at lower wavelength.
