Novel green small-molecule host materials for solution-processed organic light-emitting diodes

10.1246/cl.2008.1150

The research focuses on the development of novel green-fluorescent small-molecule host materials for solution-processed organic light-emitting diodes (OLEDs). The study introduces 9,10-diarylanthracene and fluorene moieties to the anthracene core to enhance amorphous characteristics, leading to materials with strong optical, electrical, and thermal properties, as well as good solubility in organic solvents. The experiments involved the synthesis of two anthracene derivatives, FADPA and FADNA, using Suzuki coupling reactions with aryl bromides and 2-bromoanthraquinone. The optical and electrical properties of these materials were analyzed using UV-visible spectroscopy, cyclic voltammetry, and photoluminescence (PL) spectra. Thermal stability was assessed through differential scanning calorimetry (DSC) and thermogravimetric analysis (TGA). The synthesized materials were then applied as hosts in green fluorescent OLEDs with C545T as the dopant material, and their performance was evaluated through electroluminescence (EL) measurements. The study demonstrated that these novel hosts could achieve high current efficiencies of up to 7.8 cd/A with a conventional green fluorescent dopant, showcasing their potential for use in efficient OLEDs.
