  • A new class of organic nanoparticles with a mean diameter of ca. 30−40 nm, which exhibit a strongly enhanced fluorescence emission, were prepared by a simple reprecipitation method
  • The Altmetric Attention Score is a quantitative measure of the attention that a research article has received online
  • CN-MBE is very weakly fluorescent in solution, but the intensity is increased by almost 700 times in the nanoparticles
  • Enhanced emission in CN-MBE nanoparticles is attributed to the synergetic effect of intramolecular planarization and J-type aggregate formation in nanopaticles
  • On/off fluorescence switching for organic vapor was demonstrated with CN-MBE nanoparticles
