Abstract:

Polymer-wrapping has enabled the sorting and purification of large amounts of semiconducting and monochiral single-walled carbon nanotubes (SWNTs) that can be applied in a wide range of optoelectronic devices. Their near-infrared emission properties can be tuned either by intentional doping and non-covalent functionalization [1], or by the controlled introduction of luminescent sp3-defects [2]. Furthermore, photoluminescence and electroluminescence spectra can provide information about charge transport in operating devices based on nanotube networks with and without defects [3]. Here, I will give an introduction and overview of recent progress on targeted and controlled functionalization of polymer-wrapped semiconducting SWNTs and the resulting photophysics with regard to strong light-matter coupling [4], single- photon emission and electroluminescence.
