"Enantiomers of Single-Wall Carbon Nanotubes Show Distinct Coating Displacement Kinetics." <i>The Journal of Physical Chemistry Letters,</i> 9, no. 13 (2018) American Chemical Society: 3793-3797. https://doi.org/10.1021/acs.jpclett.8b01683.https://hdl.handle.net/1911/103242It is known that specific oligomers of single-stranded DNA (ssDNA) can show remarkable selectivity when coating different structural species of single-wall carbon nanotubes (SWCNTs). We report that (ATT)4ﾠssDNA coatings strongly distinguish between the two optical isomers of (7,5) SWCNTs. This causes resolvable shifts in their fluorescence spectra and differences of 2 orders of magnitude in the room temperature rates of coating displacement, as monitored through changes in nanotube fluorescence wavelength and intensity on exposure to sodium deoxycholate. During coating displacement, the enantiomer with high affinity for the ssDNA oligomer is deduced to form an intermediate hybrid that is not observed for the low affinity enantiomer. These results reveal that enantiomeric differences in SWCNTs complexed with ssDNA are more diverse and dramatic than previously recognized.engThis is an author's peer-reviewed final manuscript, as accepted by the publisher.
