Abstract

In order to study the synthesis and characterization of two novel fluorene emitting materials for application to organic light emitting diodes, the 3, 3'', 6, 6''-tetra-tert-butyl-9'-(7-(3, 6-di-tert-butyl-9H-carbazol-9-yl)-9, 9-didodecyl-9H-fluoren-2-yl)-9'H-9, 3', 6', 9''-tercarbazole (TM1) and 9', 9''''-(9, 9-didodecyl-9H-fluorene-2,7-diyl)bis(3, 3'', 6, 6''-tetra-tert-butyl-9'H-9, 3', 6', 9''-tercarbazole) (TM2) have been constructed using well-known Ullmann coupling reaction. Nuclear Magnetic resonance spectroscopy, Mass spectrometry and FT-IR spectroscopy were used to confirm the structures of the target molecules. The carbazole-fluorene dual core of the resulting material is beneficial for their morphology, conjugation length and solubility. The physical and optical properties of them will be compared. These molecules will be used as emitting materials in organic light emitting diodes.
