Abstract:
Volatile organic compounds (VOCs) pose a major environmental and health concern, motivating the development of solid-state optical sensing materials that are both responsive and easily manufacturable. Here we introduce a new family of donor-substituted coumarin thermally activated delayed fluorescent emitters and embed them within photocurable acrylate resins. These materials retain strong solid-state photoluminescence and can be 3D-printed into functional sensing architectures that exhibit reproducible and analyte-dependent, intensity-based optical responses to chemically diverse VOC vapors. This work demonstrates how tailored emitter design and 3D printing can be combined to realize versatile VOC-responsive optical materials.
