Description

technical field [0001] The invention relates to the technical field of complex preparation, in particular to a supramolecular heterometallic complex with a two-dimensional network structure and a preparation method thereof. Background technique [0002] Supramolecular compounds have been widely used in the fields of photochemistry, piezoelectric chemical sensors, molecular recognition, molecular devices, catalysis, and chemical analysis. At present, supramolecular compounds with network structure are mainly realized by self-assembly method, among which the network structure formed by coordination and hydrogen bonding is more, and the network structure formed by π…π stacking interaction is less . This is mainly due to the weak interaction between individual molecules in supramolecular compounds. Relatively speaking, the π…π stacking interaction is weaker than the hydrogen bond interaction. In a few cases, the π…π stacking interaction The network structure formed by the inte...
