Resumen
[ES] La funcionalización no covalente de materiales de base grafénica permite introducir grupos funcionales variados sobre su superficie sin alterar la estructura del esqueleto carbonado de las láminas grafénicas.
En este trabajo de fin de grado hemos sintetizado y caracterizado dos nuevos bolaanfífilos de igual brazo pero distinto núcleo aromático, ambos diseñados para establecer interacciones de tipo n-n con las superficies grafénicas efectivas.
De estas dos nuevas moléculas así como de un derivado de naftalenodiimida similar, se ha estudiado también su comportamiento en disolución acuosa con la intención de conocer cuál de tres núcleo es el la más recomendable para su utilización en posteriores trabajos de adsorción sobre materiales grafénicos modificados.
Las buenas características observadas en uno de los compuestos sintetizados nos lleva a concluir que el núcleo de 3,6-difeniltetrazina es un buen candidato para construir nuevos compuestos dirigidos a funcionalización no covalente de superficies grafénicas.
[EN] The non-covalent functionalization of the graphene allows the introduction of various functional groups on its surface without changing the structure of the carbon skeleton of the graphene sheets. In this TFG we have synthesized and characterized two new bolaamphiphiles which have different aromatic nucleus, both designed to establish effective interactions 11:-1c with the graphite surfaces. We have also studied the behavior of these two new molecules, as well as a similar naphthalenediimide derivative, in aqueous solution to know which of three nulei is the most appropiate for its use in subsequent works about adsorption on modified graphenic materials. On the bases of the good behavior observed in one of the synthesized compounds, we conclude that the 3,6-diphenyltetrazine nucleus is a good candidate for building new efective compounds to a non-covalent functionalization of graphene surfaces.
