Axis 4 — Towards the total synthesis of Single-Walled Carbon Nanotubes

The synthesis of conjugated carbon nanorings is now a hot topic actively developed by several groups all over the world, since the pioneering work from Jasti and Bertozzi in 2008.These molecules are of particular importance, as they can be considered as Single Walled Carbon NanoTubes (SWCNT) short segments, opening the way towards the total synthesis of “armchair-type” nanotubes.
Recently, our group reported a very simple synthesis of another family of SWCNT short segments (of the so-called “zig-zag type”) using calixarenes as templates to preorganise small aromatic units (an example is given in figure A). Very recently, we used the same synthetic strategy to introduce extra aromatic units on the previous segments, allowing for simple lengthening strategies to be envisioned (an example is given in Figure B).
We also show that our approach offers the possibility to obtain new families of macrocyclic compounds, with interesting optic/electronic properties (Figure C).
