The size is tuned by the polymer/ion ratio while the helical sense is modulated by the polymer/cosolvent (i.e., MeCN) ratio. In this way, the helicity and the size of the nanoparticles can be easily interconverted by very simple experimental changesengNanospheresNanotubesHelicesPoly(phenylacetylene)sHelical senseSimultaneous Adjustment of Size and Helical Sense of Chiral Nanospheres and Nanotubes Derived from Axially Racemic Poly(phenyl acetylene)sjournal article10.1002/smll.2016023981613-6829open access
