Startling results in synthetic chemistry presented in Nature Chemistry

ter the tiniest molecules. In fact in the regularly arranged polymers there are small defined holes with a diameter in the sub-nanometer range. Moreover, tiny hexagons in the polymers, formed by benzene rings with three ester groups, can be removed by a simple hydrolytic process. This would form a sieve with an ordered structure suitable for the selective filtration of molecules.

However, before the researchers can think about practical applications, the task now is to characterize the material's properties. First of all they must find a way to produce larger amounts and even larger sheet sizes. The size of the crystals is currently only 50 micrometers. Sakamoto stresses that those, however, are already enormous degrees of polymerization at a molecular level.
