Title:
ORGANIC MOLECULE FOR OPTOELECTRONIC DEVICE
Document Type and Number:
WIPO Patent Application WO/2023/163533
Kind Code:
A1
Abstract:
The present invention relates to a pure organic molecule (without a metal center) and a use of the pure organic molecule as an emitter or absorber in an optoelectronic device. According to the present invention, the pure organic molecule includes a structure of formula A below. Here, (Het)Ar is a conjugated organic group selected from the group consisting of unsubstituted and substituted aromatic, heteroaromatic, and conjugated double bonds immobilized by cis-trans isomerization, D is a chemically bonded donor group having electron donating properties, A is a chemically bonded receptor group having electron accepting properties, and A and D are bonded to neighboring atoms of (Het)Ar.
