Intramolecular through-space heavy-atom effect in multiresonant thermally activated delayed fluorescence emitters with 2.2paracyclophane

Key Points

• The research aims to investigate how the heavy-atom effect enhances spin-orbit coupling in multiresonant TADF emitters.
• Assessed the impact of intramolecular heavy-atom effects on TADF emitters
• Analyzed fluorescence efficiencies and spin-orbit coupling mechanisms
• Increased spin-orbit coupling was observed, leading to accelerated reverse intersystem crossing.
• Fluorescence efficiency improved due to enhanced heavy-atom effects.
