Abstract
Adducts are described formed between pyrrole derivatives of formula (I) an carbon allotropes in which the carbon is sphybridized, such as for example carbon nanotubes, graphene or nanographites, carbon black. The pyrrole derivatives bear substituents on the nitrogen atom suitable for improving the physicochemical characteristics of said allotropes. A process for preparing said adducts is also described. The adducts are formed with a pyrrole of formula (I) wherein X is selected from the group consisting of: The other substituents are as defined in the claims.
