A multi-stimuli-responsive supramolecular polymer from γ-Cyclodextrin and Viologen for dual-mode display and ammonia/amines sensing

Key Points

• The supramolecular polymer effectively detects ammonia and amines, which is crucial for environmental monitoring.
• Significant improvements in sensitivity and response time were achieved compared to traditional sensors.
• Analysis of the interactions between γ-cyclodextrin and viologen demonstrated key molecular mechanisms of responsiveness.
• Further research is needed to explore broader applications beyond current sensing capabilities.
