Anorganische 2D Nanomaterialien als potentielle Bausteine für supramolekulare Chemie
Zusammenfassung der Projektergebnisse
In summary, the first phase of the Emmy Noether project “Towards supramolecular chemistry with inorganic 2D-nanomaterial building blocks” was focused on developing strategies to chemically dope liquid phase exfoliated layered materials through noncovalent interactions with various molecules and polymers. It could be demonstrated that the overall project idea is indeed a feasible approach. During the course of the project, a number of other aspects evolved that could not have been anticipated by the time the research was proposed. To be able to pursue these timely subjects, part of the planned research was redirected. The majority of the projects were highly collaborative bringing together the expertise of various groups (from chemical synthesis to theoretical physics). Our team now pursues research aspects that evolved during the Emmy Noether funding such as defect functionalisation and degradation, fabrication of heterostructures from liquid-liquid interface assembly, exfoliation of exotic materials including organic molecular crystals, selective destruction of small nanosheets, as well as further understanding the mechanism of LPE and size selection.
