| Resumo: | Graphene is nowadays the most popular nanomaterial due to its excellentmechanical, electronic, and thermal properties. However, two major drawbackshamper its implementation in practical applications: its lack of solubility incommon solvents and its relative inert surface. To overcome such setbacks,both covalent and non-covalent chemical methods have been investigated inrecent years. The covalent functionalization results in stable products, butimplies the saturation of some of the double bonds affecting the electronicproperties of graphene, whereas the non-covalent functionalization allows itssolubilization while preserving the structural and electronic features.Within this general perspective, the main aim of this PhD work was to explorethe chemical modification of graphene with different electroactive moleculesthrough non-covalent interactions, specifically π-π stacking, which preservesthe π-conjugated system of graphene. We have prepared different molecularreceptors endowed with one (monopodal derivatives) or three pyrene units(tripodal derivatives), which favor the interactions between these systems andthe basal plane of graphene through π-π stacking interactions. In addition, thesereceptors have been decorated with different electroactive moieties (π-exTTF,porphyrins and C60), in order to modulate the electronic properties of graphene... |
