    Tesis inédita de la Universidad Complutense de Madrid, Facultad de Ciencias Químicas, Departamento de Química Orgánica, leída el 25/10/2019Accomplishing the great level of complexity and sophistication of natural systems is presented as a major challenge to scientists. A multidisciplinary approach is intended to design and create the next generation of advanced materials and, in this regard, supramolecular chemistry can play a key role. In particular, the combination of organic molecules and biomolecules has appeared as a fascinating approach to take advantage of the self-assembling properties and great specificity of the biological systems to obtain materials with enhanced photophysical features. Peptides and proteins are crucial components in living beings and have demonstrated their versatility to construct artificial systems. Although great progress has been made in terms of control and diversity of structure, translating structure into functionality still remains as a major challenge...Conseguir el gran nivel de complejidad y sofisticación que presentan los sistemas naturales constituye un gran reto científico.

    Water soluble 2D crystalline monolayers of fullerenes grow on planar assemblies of engineered consensus tetratricopeptide repeat proteins. Designed fullerene-coordinating tyrosine clamps on the protein introduce specific fullerene binding sites, which facilitate fullerene nucleation. Through reciprocal interactions between the components, the hybrid material assembles into two-dimensional 2 nm thick structures with crystalline order, that conduct photo-generated charges. Thus, the protein-fullerene hybrid material is a demonstration of the developments toward functional materials with protein-based precision control of functional elements

    Repeat proteins with engineered tyrosine clamps provide a platform for fullerene assembly into 2D crystalline materials with long range molecular order and photogenerated charge carrier capacity. Thus, the self-assembling hybrid material allows to utilise the innate properties of fullerenes, demonstrating the potential of engineered protein-based functional materials
