AIE-Integrated D–A–D-Structured Dual-State Emissive Coumarin Derivative: Applications in pH Sensing, Vapor Luminescence, and Latent Fingerprint Detection
A donor−π–acceptor−π–donor (D–A–D) fluorophore exhibiting aggregation-induced emission (AIE) and dual-state emission (DSE) characteristics was developed and found to display excellent photophysical properties in both solution and aggregated states. The thermodynamically favored E-configuration of the fluorophore was...
