Poly(dithiazolfluorene-alt-thiadiazolobenzotriazole) (PSN) Nanoparticles

Size controllable conjugated polymer nanoparticles, with fluorescence spanning the spectral range from far-red to short wavelength infrared.


  • Based on a donor-acceptor-type conjugated polymer from a poly(dithiazolfluorene-alt-thiadiazolobenzotriazole) (PSN)
  • Large absorption cross-section and high fluorescence saturation intensity (as high as 113 kW·cm–2)
  • Detection of single particles as small as 14 nm through millimeter-thick turbid media
  • Exhibit a subnanosecond excited-state lifetime.
  • Could be useful for deep-tissue imaging
