Shape Prediction for Supramolecular Organic Nanostructures: [4 + 4] Macrocyclic Tetrapods

Two [4 + 4] imine cages were synthesized with a unique macrocyclic tetrapod shape. The 3-dimensional structures of both molecules were predicted a priori by using conformer searching routines, illustrating a computational strategy with the potential to target new organic molecules with shape-persistent, intrinsic pores. These methods, in combination with crystal structure prediction, form part of a broader strategy for the computationally led synthesis of functional organic solids.
