Resumen

Purpose and study method: Coordination complexes with main group elements offer an interesting alternative for the preparation of molecular materials with luminescent properties. These materials compared with their inorganic analogues, and organic polymers offer the versatility and reproducibility of the synthetic process. It is important to notice that have been reported organic compounds boron mostly derivatives of bidentate ligands with interesting photo, and electroluminescent properties. However studies of boron compounds derived from tridentate ligands have been scarcely explored. Based on the above this work research were synthesized six new compounds derived from tridentate ligands with potential application 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 five new structures of tridentate ligands and boron compounds, which were characterized by spectroscopic and spectrometric techniques and x-ray diffraction. The same way the photophysical parameters, thermal and non linear properties of all materials were studied. In some cases it was possible to carry out theoretical studies in order to analyze in depth the luminescent response. Electroluminescent devices type OLED were fabricated with the boron compounds 9a and 10a obtained as a results current-voltage curves, indicating that these materials have capable a poor electroluminescent performance.
