Cover Picture: Influence of Polymer Electronics on Selective Dispersion of Single‐Walled Carbon Nanotubes (Chem. Eur. J. 41/2016)

In the pursuit of next‐generation polymers for the selective dispersion and purification of single‐walled carbon nanotubes (SWNTs), understanding the key parameters dictating polymer selectivity is imperative. Simple modification of a poly(fluorene‐co‐pyridine) backbone, such that it is transformed from being electron‐rich to ‐poor, has a significant impact on the electronic nature of the SWNTs dispersed. The unmodified copolymer bearing an electron‐rich fluorene co‐monomer preferentially forms stable colloids with sc‐SWNTs, while the methylated copolymer bearing electron‐withdrawing cationic charges produces dispersions that are more enriched with m‐SWNTs. This work provides a clear indication that polymer electronics plays an important role. More information can be found in the Full Paper by A. Adronov et al. on page 14560 ff.
