Direct observation of backbone planarization via side-chain alignment in single bulky-substituted polythiophenes [Physics]

The backbone conformation of conjugated polymers affects, to a large extent, their optical and electronic properties. The usually flexible substituents provide solubility and influence the packing behavior of conjugated polymers in films or in bad solvents. However, the role of the side chains in determining and potentially controlling the backbone...
