Effect of Metal Nanoparticles on the Optical Properties of the Solutions of Porphyrinates and MEH-PPV Polymer

摘要

The interactions of metal nanoparticles, which were synthesized in inverse micelles, with a number of porphyrinate molecules and a poly[2-methoxy-5-(2-ethylhexyloxy)-1,4-phenylenevinylene] (MEH-PPV) polymer in solutions were examined by spectrophotometry in order to study the effects of various additives on the efficiency of sun energy absorption and conversion by photosensitive polymer layers. The optical absorption and luminescence spectra of the solutions of Ag, Pd, and Pt nanoparticles and the solutions of Pd(II) and Pt(II) meso -tetra(benzo-15-crown-5)porphyrinates and the MEH-PPV polymer were measured previously.
