Panigrahi, S K (2014) Synthesis and photophysical studies of bipolar host materials for phosphorescent oleds. MSc thesis.
The remarkable progress of light-emitting organic semiconductors has led to the establishment of organic light-emitting diodes (OLEDs) as a major display technology. Furthermore, it has opened new directions for materials and devices, and exciting new applications. In the present work, three efficient organic green to yellow emitting bipolar materials, 3-(4-(diphenylamino)phenyl)-1-phenylprop-2-en-1-one (DPPO), 3-(4-(9H-carbazol-9-yl)phenyl)-1-phenylprop-2-en-1-one (CPPO) and 4-(bis(4-(diphenylamino)phenyl)amino) )-1-phenylprop-2-en-1-one (BDPPO) were synthesized. The bipolar materials were characterized by 1H NMR, 13C NMR, Mass, UV-Visible, TGA-DTA and PL spectroscopy techniques. The synthesized phosphor materials are emitting green to yellow color with good emission intensity and can be used in the white light emitting LEDs.
