Drechsler, Susanne Balog, Sandor Kilbinger, Andreas F. M. Casalini, Tommaso 2019-09-18 Self-assembly has proven to be a powerful tool for functional, smart materials such as hydrogels derived from low molecular weight compounds. However, the targeted design of functional gelators remains difficult. Here, we present a set of four Y-shaped aromatic amide tetramers with varying functionalities able to undergo different non- covalent interactions. These compounds were explored towards their self-assembly behavior and hydrogel formation by experimental methods such as UV-vis spectroscopy, rheology, small angle X-ray scattering (SAXS), scanning/transmission electron, and atomic force microscopy. Additionally, we investigated the main mechanisms behind oligomer aggregation and the structure of the resulting supramolecular chains through full atomistic molecular dynamics simulations. application/pdf https://folia.unifr.ch/global/documents/308019 https://folia.unifr.ch/documents/308019/files/kil_isg.pdf https://folia.unifr.ch/documents/308019/files/kil_isg_sm.pdf eng info:eu-repo/semantics/altIdentifier/doi/10.1039/C9SM00148D info:eu-repo/semantics/openAccess License undefined Soft Matter. - 2019, vol. 15, no. 36, p. 7250–7261 info:eu-repo/classification/udc/54 The influence of substituents on gelation and stacking order of oligoaramid – based supramolecular networks http://purl.org/coar/resource_type/c_6501
