  • Publication number: 20230354693
    Abstract: The present invention relates to a composition of a superfluorescent cerium (III)-containing chelate having ultra-short decay time, especially a molecular composition for OLED applications, having a neutral donor in the form of a Ce(III) chelate and a neutral fluorescent receptor molecule. The composition of the present invention can be used to produce pure color luminescence with very short emission decay time, especially for a dark blue luminous region. The composition utilizes an excited state dual capture mechanism, and such kind of novel exciton capture mechanism can be classified into a fifth-generation organic light-emitting diode (OLED) and other photoelectric devices.

  • Patent number: 11404645
    Abstract: The invention relates to novel pure organic emitter molecules and optoelectronic devices containing these organic emitter molecules. According to the invention, in the optoelectronic device, after the excitation of an organic molecule, relaxation and intersystem crossing processes also result from the almost isoenergetic charge transfer triplet state (3CT) for the direct rapid occupation and emission of the charge transfer singlet state (1CT), so that a 1CT?S0 fluorescence occurs without a thermal activation.

  • Publication number: 20140364611
    Abstract: Organo-metallic complexes for opto-electronic and sensory devices and their use in such devices are provided. The organo-metallic complex (triplet emitter) consists of a metal center and chelate ligands. At least one of chelate ligands comprises an aromatic or fused aromatic ring(s). Each ligand is covalently substituted with at least one, preferably two charge transport groups (ctg). The metal center can be coordinated by a spectator ligand. Presence of two ctgs at each ligand is advantageous for applications in organic light emitting diodes (OLEDs). Charge transport units facilitate hole and/or electron transport to the molecular center and allow for efficient exciton formation directly on the complex. Presence of ctgs on each ligand provides a good shielding with respect to interactions with the environment. Emission quenching is strongly reduced and materials with high emission quantum yields are obtained.
