During the last ten years, our research group has been applying metal-mediated self-assembly processes to the construction of multiporphyrin functional assemblies. The construction of well-defined and discrete supramolecular structures resulting from self-assembly requires the use of multiple and separated connections operating in one or more closed loops. Consequently, the great majority of the multiporphyrin assemblies that we have prepared are of cyclic nature. We have placed special emphasis not only on the characterization in solution of the formed assemblies but also on the thermodynamic characterization of the assembly process and in the assessment of cooperativity. Finally, we also present examples in which functionality has been derived from the three-dimensional structures of multicomponent assemblies.

AbstractHerein, the first example of a co-crystal system formed by an imidazolium nitrate, a carbene precursor, and copper (II) nitrate, {[Cu(NO3)2(H2O)2]L1(NO3)2} (1) (L1 = 1,1′-dibenzyl-3,3′-butyl-diimidazolium-2,2′-diylidene) is reported. These two building blocks are connected in the solid state through hydrogen bonds to generate a three-dimensional supramolecular network.

Surface Chemical Modification

In recent years, block copolymer lithography has emerged as a viable alternative technology for advanced lithography. In chemical-epitaxy-directed self-assembly, the interfacial energy between the substrate and each block copolymer domain plays a key role on the final ordering. Here, we focus on the experimental characterization of the chemical interactions that occur at the interface built between different chemical guiding patterns and the domains of the block copolymers. We have chosen hard X-ray high kinetic energy photoelectron spectroscopy as an exploration technique because it provides information on the electronic structure of buried interfaces. The outcome of the characterization sheds light onto key aspects of directed self-assembly: grafted brush layer, chemical pattern creation and brush/block co-polymer interface.

The preparation and morphological characterization of a so-called composite membrane based on a 3-miktoarm star terpolymer on a support layer is reported. It is demonstrated that different levels of order and different morphological orientations can be obtained by directly casting the star terpolymer solution on the support, depending on the prior treatment of the support layer and the casting conditions.
