Semiconducting π-conjugated polymers are promising materials for applications such as light-emitting diodes, field-effect transistors, photovoltaics and optoelectronics devices thanks to their easily tuneable electrical, optical and magnetic properties. The organic materials are also easy to fabricate and are mechanically strong. Now, a team of researchers at the University of California at Berkeley and the Lawrence Berkeley National Laboratory has come up with a new way to make these polyacetylene-derived polymers and has also analysed individual chains of oligo-(E)-1,1′-bi(indenylidene) using advanced scanning probe microscopy techniques. The study has revealed how oligomer chains actually form and provides new insights into the relationship between the chemical structure and the electronic properties of the chain molecules…….
