A supramolecular polymer and its composite with carbon nanotubes, CNTs, are described. The supramolecular polymer is an ensemble of precursors that independently contain “sticky feet” for non-covalent binding to carbon nanotube surfaces and associative groups. There is at least one of the associative groups covalently bound to each of the precursor and there is at least one covalently connecting moiety connecting associative groups within a precursor or connecting an associative group to a linker to a “sticky foot” in a precursor. When the associative groups are in a dissociative state, the supramolecular polymer precursors and CNTs can be combined to form a dispersion. Upon promotion, the dissociated associative groups in the dispersion can associate to yield a CNT/supramolecular polymer composite.
The invention relates to novel 2-heteroaryl carboxamides and to the use thereof for producing medicaments for the treatment and/or prophylaxis of diseases and for improving perception, concentration, learning and/or memory.
