Conjugated bis and poly(dioxaborole)s for optical sensing of Lewis bases based on main-chain perturbations

Fluorene-based bis(dioxaborole)s and a poly(dioxaborole) were used to optically detect Lewis bases. Studies of the binding mechanism and signal transduction indicated that the response from these dioxaboroles was sensitive, reversible and cross-reactive. The polymer exhibited enhanced response due to extended conjugation through the dioxaboroles.

Influence of Polymer Electronics on Selective Dispersion of Single-Walled Carbon Nanotubes

The separation and isolation of semiconducting and metallic single-walled carbon nanotubes (SWNTs) on a large scale remains a barrier to many commercial applications. Selective extraction of semiconducting SWNTs by wrapping and dispersion with conjugated polymers has been demonstrated to be effective, but the structural parameters of conjugated polymers that dictate selectivity are poorly understood. Here, we report nanotube dispersions with a poly(fluorene-co-pyridine) copolymer and its cationic methylated derivative, and show that electron-deficient conjugated π-systems bias the dispersion selectivity toward metallic SWNTs. Differentiation of semiconducting and metallic SWNT populations was carried out by a combination of UV/Vis-NIR absorption spectroscopy, Raman spectroscopy, fluorescence spectroscopy, and electrical conductivity measurements. These results provide new insight into the rational design of conjugated polymers for the selective dispersion of metallic SWNTs.
