One-dimensional organic nanowires and nanoribbons represent idealized model systems for investigating charge transport mechanisms at molecular length scales. However, there are significant difficulties associated with the synthesis of organic nanowires and nanoribbons with precisely defined sequences, lengths, geometries, and terminal functionalities. By drawing inspiration from nature and bioconjugate chemistry, we have developed facile strategies for the covalent assembly of organic semiconductor building blocks into well-defined one-dimensional ensembles. We have investigated the properties of such ensembles with a suite of spectroscopic, electrochemical, and computational techniques, discovering exciting emergent properties. Our findings hold significance both for fundamentally understanding nanoscale charge transport phenomena and for the ultimate development of next-generation molecular electronic devices.
