Chiral Nanomaterials with Tuneable Chiroptical Properties

Abstract

This Thesis Dissertation is focused on the development of novel hybrid materials based on poly(phenylacetylene)s (PPAs) and metal nanoparticles. PPAs are a family of dynamic helical polymers where the secondary structure (helical sense and/or elongation) can be modulated by external stimuli (temperature, polarity of solvents, metal ions). Thus, they are excellent candidates to act as protecting agents of metal nanoparticles and give a chiral environment to form stimuli-responsive hybrid materials. Besides, this dynamic behaviour is affected by the strength interaction between the PPAs and metal nanoparticles
