Design and Applications of Molecular Frameworks

Control of the crystal structure in the molecular scale is of great importance due to the deep connect between the macroscopic properties and microscopic structures. Our group has developed a large library of organic crystalline materials based on the hydrogen bond interaction between guanidinium (G) cation and organosulfonate (S) anions, which enables a predictable approach to obtain quasi-hexagonal charge assisted hydrogen-bonding frameworks. Because of the extraordinary structural robustness, a diverse range of functional guest molecules can be encapsulated in the GS framework to form a new class of functional inclusion compounds, such as solid state laser dyes and conductive materials. Meanwhile, the size and shape selective effect of the GS frameworks can also provide a new route for chemical separations that are typically difficult to achieve using traditional method.
