A New Method to Polymerize the Water Soluble Conjugated Polymer MPS-PPV and the Studies on the Fluorescence Wavelength Regulation

  • Received:2009-04-30 Revised:2009-07-29 Published:2010-02-04

A new rapid polymerization method with high polymerization yield was developed to prepare
the water-soluble fluorescent conjugated polymer poly(5-methoxy-2-propyloxy sulfonate phenylene vinylene)
(MPS-PPV) in the solution of NaOH/C2H5OH/DMF. The regulation of the fluorescence emission
wavelength was realized by changing the concentration of NaOH. The polymer was characterized by elemental
analysis and infrared absorption spectrum. The molecular weight was measured by static light scattering
experiments. The fluorescence spectra and UV-Vis spectra of MPS-PPV under different polymerization
conditions were also explored. The effect of hydrogen peroxide on the fluorescence intensity and wavelength
of MPS-PPV was studied, which will provide guidelines to develop the novel fluorescence polymer-
based sensors.

Key words: conjugated polymer, poly(5-methoxy-2-propyloxy sulfonate phenylene vinylene) (MPS-PPV), polymerization, regulation, hydrogen peroxide
