This work reported the synthesis by mechanochemical method of a small molecule of the oligophenylene (bisquinoline) design (OBM), with excellent optical and electrical properties, and potential use as an electroluminescent material in the form of a nano-film in the manufacture of an organic light-emitting diode (OLED). OBM was chemically characterized by H-1-NMR, C-13-NMR, FT-IR spectroscopy, and AccuTOF-DART mass spectrometry, and its optical properties were obtained using UV-Vis and fluorescence spectroscopies. The OBM film exhibited high homogeneity, allowing the manufacture of an OLED device with a luminance of 2350 cd/m(2) under specific conditions.
In this work is report the synthesis by mechanochemical method of a small molecule of the oligophenylene (bisquinoline) design (OBM), excellent optical and electrical properties, and potential use as an electroluminescent material in the form of a nano-film in the manufacture of an organic light-emitting diode (OLED). OBM was synthesized by a Knoevenagel condensation reaction and was chemically characterized by H-1-NMR, C-13-NMR, FT-IR spectroscopy, and AccuTOF-DART mass spectrometry. UV-Vis and fluorescence spectroscopies were used to obtain the optical properties of OBM, both in solution and in film. Also, the OBM film was examined by atomic force microscopy and showed a high degree of homogeneity which allowed the manufacture of an OLED device with ITO/OBM/PEDOT: PSS/Al configuration with a luminance of 2350 cd/m(2) when supplied with a fixed current of 15 mA and 10 volts.
