Non-conjugated linkers interrupt direct conjugation in the polymer backbone, providing enhanced solubility, blue TADF emitters, and high triplet energy host and hole transport materials.
This review highlights progress made in the last decade in the synthesis of thermally activated delayed fluorescence emitters through C–H bond transformations, and gives an outlook on further challenges and potential directions in this field.
The recent research progress of organic boron-containing thermally activated delayed fluorescence (TADF) materials is reviewed systematically with a focus on the molecular design, photophysical properties and performance of the corresponding OLEDs.
Nonconjugate linkers (sp3 cores) are a versatile platform for molecular design for TADF OLEDs. The introduction of an sp3 core disrupts direct conjugation between donor and acceptor units, preventing immediate charge transfer between them.
This review highlights the importance of developing color-tunable TADF, CPL TADF and MR-TADF emitters and their molecular strategies to achieve exceptional photophysical characteristics, which are crucial for advancing OLED technology.
