A t-butyl modification approach of acceptor moiety for stable deep blue emission in thermally activated delayed fluorescent devices

摘要: Abstract A t -butyl modification method of an acceptor moiety was developed as a molecular design approach blue emitters to shift the emission color deep region and stabilize according doping concentration. phenyl unit triphenyltriazine thermally activated delayed fluorescent emitter modified with either one or two units study effect on electroluminescence emitters. It found that introduced in shifted while keeping over wide concentration range.
