Abstract

A molecule-based sensor must elicit a measurable response in reaction to a specific stimulus. Ion-selective crown ether dyes are an established example of a molecular sensory component.'We are working to expand the scope of measurable responses to include chemically induced resistance changes in organic conducting polymers. It is well-known that twisting a conducting polymer's backbone from planarity can result in a conductivity drop ...
