Fluorene and carbazole derivaties have been intensively studied recently due to their electroluminescent properties. Epoxy network has good stability due to the thermal stability and good mechanical properties. It is expected that cross-linked polymeric network improves mobility due to the dipoles of the epoxy resin. In this work, we have investigated two types of cross-linked polymeric network from epoxy and 3,6-diaminocarbazole, and 2,7-diaminofluorene. The cross-linked polymers were characterized using FT-IR, UV-vis spectra, thermogravimetric analysis (TGA), photoluminescence (PL) and electroluminescence (EL) spectroscopy. Carbazole-Epoxy networks have emitted orange color and enhanced thermal stability. The detailed electroluminescent properties and hole injection ability of the LED devices using epoxy cross-linked polymeric network will be presented. |
