RT Journal Article T1 3D self-assembly of cyclic peptides into multilayered nanosheets A1 Díaz Arias, Sandra Natalia A1 Sánchez Fernández, Adrián A1 Granja Guillán, Juan Ramón A1 Insua López, Ignacio A1 Montenegro García, Javier AB The hierarchical self-assembly of three-dimensional (3D) supramolecular materials presents a significant challenge in molecular design. This process requires monomers with specific packing geometries and orthogonal contacts to enable multidimensional elongation. Here, we describe a new cyclic peptide design that allows hierarchical self-assembly in all three spatial dimensions to produce nanosheets composed of ordered nanotube layers. The uniformity of the nanosheet aspect ratio and thickness is consistent with the high packing order of the monomers observed in this 3D assembly.
