Generating simpler and less expensive OSDAs is essential to expand the palette of molecular sieves used in catalysis, separations, and ion-exchange. However, the complex interplay among synthesis conditions, including temperature, pH, precursor composition, as well as the unique structure-directing ability of organic and inorganic templates makes it difficult to predict the outcome of a particular synthesis a priori. Combining high throughput computational simulations capable of accurately predicting the interactions for thousands of OSDA-zeolite pairs with focused synthesis campaigns, we demonstrate a strategy to navigate the complex energetic landscape of templating organic molecules, identify suitable families of candidate structures, and down-select the simplest organic molecules for the synthesis of the target frameworks, including a variety of zeolite intergrowths. Overall, this work shows a new platform to find alternative organic directing agents that drive the formation of known zeolite frameworks with a higher phase selectivity, desired framework composition, or lower synthetic complexity.
