Abstract
Polyphenylacetylenes bearing prim- and secamine
groups are barely known due to their poisoning
activity towards the polymerization catalyst. 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 protonation
