Abstract
In the course of studying the properties of highly conjugated polymers, we found that long‐range orbital delocalization conferred unexpected properties. The giant electronic orbitals made these materials electroactive yet very stable. A new mode of electronic polarizability, a giant nomadic polarization, resulted, making these organic polymers among the most polarizable materials ever observed. In addition, remanent magnetization, high conductivity, and unusual pressure sensitivity could be achieved. The giant‐orbital concept opens new vistas of materials properties.
