Hybrid materials, consisting of an amphiphilic block copolymer matrix incorporating metal nanoparticles, have attracted great attention due to their unique properties, such as the catalytic behavior or the optical properties, making them potential candidates for photonic devices. High purity block copolymers, such as poly(isoprene-b-acrylic acid) (PI-b-PAA) and poly[(sodium sulfamate-carboxylate-isoprene)-b-tert-butylstyrene] (BS-SCI), have been synthesized by anionic polymerization and dissolved in selective solvents for the formation of well defined micelles. These block copolymers have been used as matrices for the in situ synthesis of gold nanoparticles either inside the dense core or at the periphery of the corona of their micelles. The systems were investigated by dynamic light scattering (DLS), UV-visible and ATR-IR spectroscopy, atomic force microscopy (AFM) and transmission electron microscopy (TEM). Additionally, the third non linear optical response of the hybrid materials synthesized has been investigated using the OKE and Z-scan techniques. The optical limiting of these systems has also been investigated.
