DIRECT SINGLET CAPTURE ORGANIC MOLECULES WITH SHORT EMISSION DECAY TIME AND APPLICATION THEREOF IN OPTOELECTRONIC DEVICES

摘要

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.
