Unraveling the mechanism of green emission peaks in single polyfluorene chains

Molecular aggregates are clusters of small molecules held together by relatively weak forces believed to be originating from electronic interactions between the molecules. Owing to their exceptional photophysical properties, molecular aggregates find unique applications in many areas of technology and continue to be a subject of intense research. In fact, researchers have utilized molecular aggregates to engineer a variety of functional materials, biomedical tools, and nanodevices.
