There is provided an aminoanthryl derivative-substituted pyrene compound represented by the following general formula (1).
The compound is useful as a compound for an organic light-emitting device exhibiting highly pure luminescent color, and an optical output with high efficiency, high luminance, and long life.
Structurally simple donor–acceptor molecule TAAB shows reversible multiple emission switching in the solid state by various external stimuli; the intermolecular interactions of C and H with the Br group play the key roles in this tunable emission system.
in a multistep reaction protocol including Sonogashira C,C‐ and Buchwald–Hartwig C,N‐ cross coupling reactions. Electrochemical and spectroscopic studies suggest a high degree of delocalization between the ruthenium and triarylamine termini through the anthracene bridge, forming a donor–π–acceptor (D–π–A) dye whose π–π* transitions exhibit charge‐transfer character in the monocationic oxidation state
The present invention relates to novel materials which can be used in organic electronic devices, in particular electroluminescent devices, and are certain derivatives of fused aromatic systems.
