(2017). The role of the secondary structure of helical poly(phenylacetylene)s in the formation of nanoparticles from polymer–metal complexes (HPMCs). Nanoscale, 9(45), 17752-17757. http://dx.doi.org/10.1039/c7nr04829g2040-3372http://hdl.handle.net/10347/16403The great importance of the secondary structure (compressed/stretched) of helical poly(phenylacetylene)s (PPAs) in the formation of nanostructures (nanospheres and nanotoroids) by complexation with metal ions of diverse valences is demonstrated. PPAs bearing the same chelating units [anilide of (R)-methoxyphenylacetic acid] but displaying different helical scaffolds show great differences in their nanostructuration due to the different secondary structures of their helices despite the analogous ways in which their mono- and divalent metal ions form complexes. This key 3-D structural feature has not been taken into account previously when studying the nanostructuration of helical polymer–metal complexes (HPMCs)eng© Royal Society of Chemistryjournal article10.1039/c7nr04829gopen access
