Research Abstract

Integration of functional molecules on the rigid helical structure of polyisocyanides leads to new functional polymers. Addition of suitable alkali metal ions to fit into the crown ether of the side chain on the helical polycyanide resulted in the deformation of the helix by electrostatic repulsion. We also found a new method to detect the helical structure by emission spectra.
