“…[28][29][30][31][32][33][34] They are typically obtained in a single step, in nearly quantitative yield, via a "coordinative self-assembly" process (Scheme 1). 31,35,36 The process makes use of Re(CO) 5 X as a simple synthon predisposed, via classical trans labilization effects, to liberate two (and only two) carbonyl ligands, exclusively from cis sites. Because the rhenium centers exist in oxidation state I (necessary for stable 18-electron organometallic complex formation), the anionic halide ligands are sufficient to reduce the overall charge to zero.…”

“…Most often observed in crystal structures is the "two up + two down (diagonal)" structure, presumably because packing is optimized, rendering this isomer easiest to crystallize. 29,35 Completing the subset are the 4,4′-bipyridine-bridged molecular rectangles, 10 and 11. These compounds have been obtained in Mn(I) and Re(I) form, via a two-step synthesis (Scheme 2).…”

An enormous number and variety of discrete, isolable, supramolecular-coordinationchemistry-based assemblies featuring well-defined nanoscale cavities have been designed, synthesized, and characterized over the past decade. A small number of these have subsequently been used as building blocks for microporous materials and now comprise an important component of an emerging chemistry of microporous molecular materials. The extant materials typically have displayed large void volumes, high internal surface areas, and the ability to withstand the systematic removal of solvent. These and other properties (chemical tailorability, alignment of cavities to form extended channels, good processability, etc.) suggest a number of potentially very exciting applications involving selective molecular transport, sensing, or chemical transformationswith many of these now supported by proofof-concept experiments.

“…25 In the literature various luminescent metallasupramolecular architectures have been reported, of which rhenium-based self-assembled molecular squares 26 and rectangles 27 occur most frequently. Examples are the molecular square 18 and triangle 19 from Lees and co-workers, which both exhibited luminescence in solution at room temperature.…”

The synthesis of metallasupramolecular architectures, such as two-dimensional squares, triangles and polygons, and three-dimensional cages and polyhedra, has attracted much interest in the past decade. These structures are designed to have novel specific shapes and dimensions with interesting functional properties. In this overview the functional properties of metallasupramolecular architectures are highlighted with emphasis on potential applications such as catalysis, cavity-directed synthesis and sensing, that can be performed with these materials.

“…Podemos distinguir dois tipos de estratégias: a) o complexo metálico é introduzido para promover a automontagem coordenativa de dois ou mais componentes de complexos supermoleculares, ou b) os complexos metálicos são utilizados como componentes ativos das supermoléculas. Vários íons metálicos podem ser utilizados, mas os complexos de rutênio 10,12 , paládio e platina 21,22 têm sido mais freqüentemente empregados. Os complexos de rutênio, principalmente com ligantes polipiridínicos como a 2,2-bipiridina e a terpiridina, têm sido largamente empregados em função de sua estabilidade e propriedades fotoquímicas.…”

Recebido em 12/7/01; aceito em 5/3/02 CHEMISTRY OF SUPRAMOLECULAR SYSTEMS CONTAINING PORPHYRINS AND METAL COMPLEXES. Supramolecular chemistry is expected to keep a high developing pace in the next years, giving support to the advancement of molecular devices and nanotechnology. In this sense, porphyrins and their analogues should play a significant role as a consequence of their catalytic, electrocatalytic, photochemical and photoelectrochemical properties. In this review we focused on our own strategy based on coordination chemistry for the design and build-up of supermolecules and supramolecular structures constituted by polynuclear porphyrins and metalloporphyrins. Included are also their properties and potential applications.
