Fluorescence spectroscopy offers sensitive, non-destructive analysis. Fluorescent probes in polymers act as sensors, enabling in-situ monitoring of microenvironment changes for various applications.

Area of Science:

  • Analytical Chemistry
  • Materials Science
  • Polymer Science

Background:

  • Fluorescence spectroscopy is a highly sensitive and selective analytical technique.
  • Intrinsic fluorescence of materials like polymers is often unspecific.
  • Fluorescent probes are needed to correlate fluorescence with microenvironment changes.

Purpose of the Study:

  • To explore the use of fluorescent probes in polymers as sensors.
  • To enable in-situ monitoring of dynamic processes within polymer systems.
  • To correlate fluorescence measurements with local parameter changes.

Main Methods:

  • Incorporation of fluorescent additives into polymer matrices.
  • Utilizing fluorescence emission sensitivity to microenvironment properties (polarity, fluidity, pH, etc.).
