Abstract:
A simple strategy is presented for the bifunctional detection of environmental organic vapor and temperature by utilizing H-bond interactions to trap a butterfly-vibration-based fluorophore (DPAC-OH) in a polyurethane (PU) matrix. The method opens up a new path for large-scale environmental inspections and the design of dual-response luminescent materials.
