Steric modulation of o -carborane enables tunable single and dual emission in multi-resonance TADF compounds

Key Points

• Single and dual emissions are achievable by adjusting steric bulk at the 2-position of the o-carborane.
• Key evidence includes the observation of distinct emissive excited states in various configurations.
• Assessment of emissive properties involved varying substituents on the o-carborane structure, emphasizing their role in TADF.
• Supports advancements in tuning photophysical properties for applications in organic light-emitting devices.
