Boosting Room-Temperature Phosphorescence via Polarity-Induced Through-space conjugation in a Host-Guest Doping System

Key Points

• The aim is to enhance room-temperature phosphorescence using polar guest molecules in a host matrix.
• Incorporation of polarity coumarin derivatives into the host-guest system.
• Evaluation of phosphorescence performance under room temperature.
• Improved phosphorescence performance due to polar guest molecules.
• Demonstrated effectiveness of through-space conjugation in the host matrix.
