제목 Poly(thiophene) Nanoparticles Prepared by Fe3+-Catalyzed Oxidative Polymerization:A Size-Dependent Effect on Photoluminescence Property
초록 Poly(thiophene) (PTh) nanoparticles with various sizes were directly prepared by Fe3+-catalyzed oxidative polymerization of thiophene with varying hydrogen peroxide (H2O2) concentrations. With increasing H2O2 molar concentration from 2.35 to 5.88 M, the average sizes of the PTh nanoparticles decreased from 51 to 12 nm, and their photoemission wavelengths shifted from red to blue color at the maximum excitation wavelength (λUVmax = 400 nm). As a result, we could tune the emitting colors that resulted from variations of the effective conjugation chain length by manipulating the size of PTh nanoparticles.
