Abstract: | Nanospheres and nanotubes with full control of their size and helical sense are obtained in chloroform from the axially racemic chiral poly(phenylacetylene) poly‐(R)‐ 1 using either Ag+ as both chiral inducer and cross‐linking agent or Na+ as chiral inducer and Ag+ as cross‐linking agent. 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 changes. |
