Abstract
Large flower sized nanoparticles of silver were synthesized and hybrid colloids with porphyrins were obtained. Daisy-like round aggregates generated from triangular-shaped silver nanoparticles can be observed, evenly distributed. The complexation of these particles with organic dyes was the main purpose of this work in order to achieve nanomaterials exhibiting wide absorption bands. The formation of a complex between an acidified Co(II) 5,10,15,20-meso-tetra(3- hydroxyphenyl) porphyrin (Co-3OHPP) solution in THF and the silver colloid negatively charged at the surface was proven by analyzing the UV-vis spectra during the experiment.
