Synthesis and Characterization of Poly(o-Methoxyaniline) Microsheets with pH-Sensitive Fluorescence Properties

Article Preview

Abstract:

Functional poly(o-methoxyaniline) (POMA) microsheets are successfully synthesized in the presence of (NH4)3[CoMo6O24H6]·7H2O (CoMo6) under acidic conditions. It is proposed that the light-green CoMo6 precipitates formed in the initial reaction systerm serve as a polymerization reaction template for the formation of POMA microsheets. Moreover, POMA microsheets show pH-dependent fluorescence and exhibit enhanced fluorescence properties in comparision with POMA synthesized by conventional method in the absence of CoMo6.
