Background:
- Covalently embedding phosphors into polymer matrices is key for efficient polymer-based room-temperature phosphorescence (RTP) materials.
- Current methods face challenges in large-scale fabrication due to inefficient binding and lengthy reaction times.
Purpose of the Study:
- To develop a scalable and efficient method for preparing polymer-based RTP materials.
- To overcome the limitations of traditional covalent binding techniques for RTP material synthesis.
Main Methods:
- Utilized a facile B─O click reaction between boronic acid-modified phosphors and a polyhydroxy polymer matrix.
- Employed ab initio molecular dynamics simulations to analyze phosphor immobilization and RTP emission mechanisms.
Main Results:
- Achieved rapid RTP material fabrication via B─O click reaction within 20 seconds under ambient conditions.
- Demonstrated effective immobilization of phosphors, suppressing nonradiative transitions and enhancing RTP emission.
- Significantly reduced reaction times compared to traditional covalent binding methods (hours).
Conclusions:
- The B─O click chemistry approach offers a simplified and rapid strategy for constructing polymer-based RTP materials.
- This method provides a viable pathway for the scale-up production of advanced RTP materials.
- The findings inspire new possibilities for developing efficient and easily fabricated phosphorescent polymers.
