Abstract
A computational method capable of predicting chemically-synthesizable organic structure directing agents (OSDAs) for targeted microporous material frameworks has been applied to the zeolite SSZ-39 (AEI framework topology). The top predicted OSDA has been found to have a more favorable stabilization energy than any of the OSDAs previously reported to form SSZ-39. This result was verified experimentally, demonstrating that this computational method is capable of predicting successful OSDAs for zeolite synthesis mixtures containing a large number of inorganic variables such as heteroatoms, inorganic cations, hydroxide media and high water content. This is a significant improvement over the first experimental validation of this computational method.
