Fluorescence Behavior of the Aqueous Solution of Phenylenediimido Cellulose
Abstract:
A polymer Schiff's base, phenylenediimido cellulose with fluorescence property was synthesized from dialdehyde cellulose with o-phenylenediamine. The optimal concentration ratio and the total concentration of the reactants were 2:1 and 6 × 10-4 g/mL, respectively. In an aqueous solution of pH 7.6 at 470 nm excitation wavelength the emission intensity of the cellulose Schiff's base reached a maximum at emission wavelength 550 nm and it then decreased with increase in the pH value of the solution.
