Résumé
The design and construction of periodic architectures in the crystalline phase are attracting considerable interest over the last two decades. For both design and analysis of molecular crystals, we have developed a strategy called molecular tectonics which is based on the formation of molecular networks through the design of complementary tectons or molecular construction units. The generation of molecular networks and subsequently of crystals is achieved by self-assembly processes based on repetitive molecular recognition events. This approach, combining supramolecular synthesis and self-assembly processes in the solid-state, is operational and versatile and allows the design and construct a variety of complex purely organic or hybrid architectures. Furthermore, molecular tectonics allows the design of core-shell crystals and crystal welding. The approach will be presented and illustrated by a variety of tectons and networks, core-shell crystals and welded crystals.
