3D-Printed Optical Volatile Organic Compound Sensors Based on Donor-Substituted Coumarin Thermally Activated Delayed Fluorescence Emitters.
Article in Small science, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

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.
