Metal-Organic Frameworks (MOFs) are ideal materials for the modular design of complex assemblies. They possess a long-range ordered hybrid structure associated with well-organized micro- or mesoporous channels and/or cages.[1] Their chemical composition (metal cation, ligand) can be easily tuned, through direct or post-synthetic methods, as well as the presence of Lewis, redox, photoactive or acid/base Brönsted centers within the framework. This large chemical versatility combined with the large structural diversity, offers a unique opportunity to generate a diversity of structures and compositions, making them of great interest for various applications such as gas storage, separation, catalysis, drug delivery, etc. In this presentation, I will describe some recent developments concerning the design of (a) Ti(IV) based photo-conductive porous hybrid solids,[2]  (b) conductive porous hybrid solids for application in electrocatalytic O2 reduction and (c) MOF @ spin crossover complexes hybrid solids for sensing applications.[3]
