Host Engineering of Deep-Blue-Fluorescent Organic Light-Emitting Diodes with High Operational Stability and Narrowband Emission.

The realization of highly operationally stable blue organic light-emitting diodes (OLEDs) is a challenge in both academia and industry. This paper describes the development of anthracene-dibenzofuran host materials, 2-(10-(naphthalen-1-yl)anthracen-9-yl)naphtho[2,3-b]benzofuran (Host 1) and 2-(10-([1,1'-biphenyl]-2-yl)anthracen-9-yl)naphtho[2,3-b]benzofuran (Host 2), namely for use in the emissive layer of an OLED stack. A multiple-resonance thermally activated delayed serves as the blue fluorescence emitter and exhibits an initial luminance of 1000 cd m and long operational stability (i.

Enhancing operational stability of OLEDs based on subatomic modified thermally activated delayed fluorescence compounds.

The realization of operationally stable blue organic light-emitting diodes is a challenging issue across the field. While device optimization has been a focus to effectively prolong device lifetime, strategies based on molecular engineering of chemical structures, particularly at the subatomic level, remains little. Herein, we explore the effect of targeted deuteration on donor and/or acceptor units of thermally activated delayed fluorescence emitters and investigate the structure-property relationship between intrinsic molecular stability, based on isotopic effect, and device operational stability.
