Resumen

Purpose and study method: Complexes derived from Schiff bases offer an interesting alternative for the synthesis of tin compounds with luminescent properties. It is important to notice that have been reported organotin compounds mostly derivatives of bidentate ligands with interesting photo, and electroluminescent properties. However, studies of tin compounds derived from multidentate ligands have been scarcely explored. Based on the above, this work research was synthesized four new compounds derived from multidentate ligands with potential application as optoelectronic device, using an organotin compound as emitter material and an electron transport layer in the assembly of electroluminescent devices type OLED. Conclusions and contributions: In this work research was reported two structures of multidentate ligands and four tin compounds, which were characterized by spectroscopic and spectrometric techniques and x-ray diffraction. The same way the photophysical parameters, thermal and cyclic voltammetry properties of all materials were studied. Electroluminescent devices type OLED were fabricated with 4 obtained as a results current-voltage curves, indicating the presence of the electroluminescence phenomenon.
