A Dual-Phase Luminescent Phosgene Sensor Based on an AIE-Active Ruthenium(II) Polypyridine Complex

Key Points

• The aim is to develop a sensor for detecting phosgene using a specific ruthenium(II) complex.
• Synthesis of bis-heteroleptic ruthenium(II) complex 1[PF6]2
• Characterization of aggregation-induced emission enhancement (AIEE) properties
• Testing the sensor's efficacy in detecting phosgene
• Compound 1[PF6]2 exhibits marked luminescent properties when exposed to phosgene
• The sensor shows significant sensitivity and specificity for phosgene detection
• Demonstrates potential applications in environmental monitoring
