Indium Sulfides with Extra-large-pore Open Frameworks

8 Indium Sulfides with Extra-large-pore Open Frameworks 

It should be noted that cations in the cavities of ASU-31 and ASU-32 can be exchanged by Na+. O Keeffe and Yaghi and coworkers[225] compared the sizes of such spheres for ASU-31 and ASU-32 with those of the most open zeolites with larger cavities. From Table 2.8, it can be seen that ASU-31 and ASU-32 exhibit the largest size of the free diameter of the cavities.

Despite the limited number of framework types reported, the number of hypothetical topologies that can be designed by computational methods is infinite (see Chapter 7). It is believed that advances in synthetic chemistry, especially the use of hydrothermal/ solvothermal combinatorial techniques, will significantly accelerate the rapid discovery of new open-framework materials with diverse framework structures.
