Organogel of fluorescein-based derivative formation in the selected pH value

Abstract

In this work, film structure was obtained by self-assembly of fluorescein derivative via sol–gel process. The self-assembly structure and the formation mechanism had been studied and certified by scanning electron microscopy, IR, UV–vis, fluorescence and X-ray diffraction experiment data. The UV–vis absorption and emission spectra of the compound 1 were changed with the change of the pH value in the solution state. This gelator had certain selectivity for pH value and formed gels.
