Title:
SPHERICAL ORGANIC PHOTOELECTRIC MATERIAL AND METHOD FOR FABRICATION THEREOF AND APPLICATION THEREOF
Document Type and Number:
WIPO Patent Application WO/2019/100914
Kind Code:
A1
Abstract:
Disclosed are a spherical organic photoelectric material and method for fabrication thereof and application thereof; said material has a non-conjugated spherical shape; the left and right edges are donor units, and the middle is a receptor unit; a certain twist angle is present between the two, and the band gap is large, and the material may readily have a relatively small EST; thus thermally activated delayed fluorescence (TADF) can be readily achieved; the invention may be adequately used as a blue-light TADF material, expanding the applications of organic light-emitting devices, particularly blue-light devices. The method for synthesizing the organic photoelectric material is relatively simple, purification is very easy, and the yield is also ideal.
