在NaOH/C2H5OH/DMF溶液中，实现了水溶性阴离子荧光共轭聚合物聚-[5-甲氧基-2-(3-磺酰化丙氧基)-1,4-苯撑乙烯](MPS-PPV)单体的快速聚合并提高了聚合产率。通过改变溶液中NaOH的浓度，实现了对聚合物荧光发射波长的调控。对聚合物进行了元素分析、红外光谱以及分子量的表征，并探讨了不同聚合条件下得到的MPS-PPV的荧光和紫外光谱变化。研究了过氧化氢对MPS-PPV荧光的影响，为基于荧光聚合物的新型传感器的研制提供了新思路。
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.
