Herein we prepare 11 different amino polymers in high yields by direct polymerization of their corresponding ammonium salts in water using [Rh(cod)2] +BF4- as catalyst. They are stable, water soluble, and show a helical structure that responds to external stimuli (polarity, pH and metal ions) acting on the pendants. The location of the amino group in the pendant is shown to be critical for the helical response to protonationengCopyright © 2018 American Chemical Societyjournal article10.1021/acs.chemmater.8b032381520-5002open access
