Back Cover: Unveiling size-fluorescence correlation of organic nanoparticles and its use in nanoparticle size determination
In this study, Peng et al. established a logarithmic relationship between the nanoparticle size and fluorescence intensity based on hydrogen-bonded supramolecular assembly and aggregation-induced emission. The logarithmic relationship arises from the different nonradiative decay rates of monomers at the surface and within the interior of the nanoparticles, which can be effectively utilized for estimating nanoparticle sizes through fluorescence intensity measurements (e415).
