N2 - Two kinds of cyanophenyl terminated pyrene derivatives for organic light-emitting diodes were synthesized and characterized by UV/Vis, fluorescence (FL), 1H NMR, MALDI-TOF, CV and TGA. Both compounds exhibited blue photoluminescence and high fluorescent quantum yield of 85% and 75% in solutions. Due to the presence of acetylene spacer, the compound distinguishes itself by high coplanarity, high thermal stability, little Stokes' shift and clear excimer formation in the solid state from the acetylene-free compound. In order to suppress the molecular aggregation, the electroluminescent properties were studied by doing the materials in PVK. The result proved that energy transfer happened from the host PVK to the materials. Two kinds of cyanophenyl terminated pyrene derivatives for OLEDs were synthesized and characterized. Both compounds exhibited blue photoluminescence and high fluorescent quantum yield of 85% and 75% in solutions. The result proved that energy transfer happened from the host PVK to the materials.
