Application

8-Hydroxypyrene-1,3,6-trisulfonic acid trisodium salt (HPTS) can be used to prepare:
  • Extruded fluorescent plastic indicator film for the detection of gaseous and dissolved CO2.
  • Highly fluorescent waterborne polyurethane (WPU) matrix which is used as a pH sensing indicator.
  • Positive (p-type) semiconducting polymeric gels via free radical cross-linking co-polymerization.
