Phys.org / Molecular chains with bite: Customized carbon nanoribbons open a cleaner path to molecular electronics

The longest chains of the conductive polymer poly(p-phenylene; PPP) produced to date are just under one micrometer (thousandth of a millimeter) long—almost an order of magnitude longer than previously possible. A research ...
