Abstract

Abstract: A novel method for attaching 3-epoxypropoxy fluorescein(EPF) to water soluble chitosan(GCS) and its dual sensitive quality of fluorescence were investigated. GCS bearing EPF was characterized by the methods of IR, ¹H NMR, UV and fluorescence spectra, respectively. The chemiluminescent and photophysical behavior of GCS-EPF were studied, and the pH and temperature dependences of fluorescence of GCS-EPF were investigated in detail. From the results, we found that the emission wavelengths of GCS-EPF in solid and film states were larger than that in solution state, which may be due to the formation of an excimer between chromophore moieties on a chitosan chain. At 0-60 ℃, the maximum fluorescence intensity of GCS-EPF decreased on heating and the relationship between fluorescence intensity and the change of temperature was linear; At pH=0-13.5, its fluorescence intensity increased with basification and completely disappeared at very acidic pH.

Key words: Epoxypropoxy fluorescein(EPF), Soluble chitosan(GCS), Fluorescence, Temperature sensitivity of the fluorescence, pH sensitivity of the fluorescence
