1 results about "Intermolecular charge transfer" patented technology

The present application relates to the field of photoelectric technology, especially to organic light-emitting material, organic electroluminescent device and preparation thereof. The organic light-emitting material based on acephenanthrylene derivative and the organic electroluminescent device thereof, the material is fused through benzene ring, ensures that the excited state has high oscillator strength, is conducive to radiation transition, and the rigid fused ring structure can effectively inhibit intramolecular vibration, helps to inhibit the non-radiative transition behavior of the excited state and obtain high photoluminescence efficiency, in addition, the molecule can form intermolecular charge transfer aggregate to reduce the non-adiabatic coupling of electrons, so as to realize low non-radiative transition rate, further improve the photoluminescence efficiency, and also can stabilize the excited state energy, can be further applied to organic electroluminescent device, realizes high electroluminescence efficiency.
