Abstract

Multicomponent supramolecular systems can be used to achieve different properties and new behaviors compared to their corresponding single component systems. Here, a two-component system is used, showing that a non-gelling component modifies the assembly of the gelling component, allowing access to co-assembled structures that cannot be formed from the gelling component alone. The systems are characterized across multiple length scales, from the molecular level by NMR and CD spectroscopy to the microstructure level by SANS and finally to the material level using nanoindentation and rheology. By exploiting the enhanced mechanical properties achieved through addition of the second component, multicomponent noodles are formed with superior mechanical properties to those formed by the single-component system. Furthermore, the non-gelling component can be triggered to crystallize within the multicomponent noodles, allowing the preparation of new types of hierarchical composite noodles.

Additional Information: Funding Information: L.J.M. thanks the Leverhulme Trust for funding (RPG‐2019‐165). SANS data were collected on beamlines SANS2d and Larmor at the ISIS Neutron and Muon Source (Science and Technology Facilities Council, Rutherford Appleton Laboratory, Oxfordshire, UK). The experiment was allocated beam time under experiment number RB2210011 (https://doi.org/10.5286/ISIS.E.RB2210011). This work benefited from the use of the SasView software, originally developed under NSF award DMR‐0520547. SasView contains code developed with funding from the European Union's Horizon 2020 research and innovation program under the SINE2020 project, grant agreement No 654000. L.J.M. would like Daniel McDowall for his guidance in preparing the noodles. M.W. thanks UKRI for a Future Leaders Fellowship (MR/T044020/1).
