Development of 3D molecular organic cages with large internal cavities has emerged as an important research area of supramolecular chemistry mainly due to their usefulness as host molecules with enhanced guest binding properties, nanoporous materials with well-defined pores and large internal surface area as well as sensors. Among the most important challenges in the achievement of such molecules we can mention their laborious multi-step synthesis and the difficulty to preserve the integrity of the internal cavity in the solid state. Herein, we propose the design and synthesis of rigid and semi-flexible naphthalene diimide-based 3D cage molecules with trigonal prismatic, square prismatic and hexagonal prismatic geometries as proper candidates to obtain materials with improved gas absorption capacities as well as selective receptors for organic small molecules. Moreover, considering the electronic and spectroscopic properties of the naphthalene diimide units, the proposed structures meet the requirements of molecular sensors. One-pot or sequential dynamic synthesis using imine exchange and/or alkynes metathesis reversible reactions in a classical dynamic covalent chemistry (DCC) process will be used in order to achieve the target structures. In addition, taking advantage of the orthogonality between the imine formation and alkynes metathesis, an Orthogonal Dynamic Covalent Chemistry (ODCC) strategy shall also be used for the synthesis of the cage compounds.
