Metals are one of the most employed external stimuli for modifying the structure of helical polymers. In poly(phenylacetylene)s it's known that can act as crosslinking agent among polymer chains, inverse the helical sense or enhance the initial helicity. Finally, nanostructures like nanospheres, nanorods, etc, can be obtained. In order to find new structures and new functions in helical polymers, this work addressed the synthesis of a novel family of materials denominated poly(diphenylacetylene)s. These polymers are a special class of conjugated polymers that present the abilities of fluorescence emission and a high thermal stability. In this work, we analyze the chiroptical properties of the synthetized polymers and how the addition of different metals can modify them. Also, fluorescent chiral nanostructures are obtained.
