Nitrogen-doped carbon-based

Very recently, TSILs having a bis-imidazolium motif linked with various organic groups may allow for the synthesis of hierarchical nanoporous nitrogen-doped carbons (Fig. 1.5). Microporous-mesoporous carbon with the specific surface area up to 1,300 m g was facilely obtained through the ionothermal synthesis process as well [34], Besides the potential good CO2 uptake abilities of these N-doped mesoporous carbons, they may also be considered as the baskets for polyamines-derived CO2 adsorbents based on their good mesoporous architectures.

Applications of CNTs based on their electrical properties strongly depend on the diameter and helicity as well as parity.2 3 Doping of CNTs by boron and nitrogen renders them p-type and retype, respectively. MWNTs and SWNTs doped with nitrogen 4 17 and boron"1 9 have been reported. Boron-doped carbon nanotubes appear to exhibit enhanced electron field emission due to the presence of the boron atom at the nanotube edges.20 2 N-doped CNTs show retype behavior regardless of tube chirality.22... 

We could show that it is possible to get n-type doping effects in carbon based materials using nitrogen as a dopant. The structures where this works, however, are purely sp bonded low energy forms of carbon. The semiconducting allotropes are characterized by unique screw axes of single bonded sp carbon atoms held...
