13. Thin molecular films of supramolecular porphyrins
A relevant series of symmetric supramolecular porphyrins has been obtained by attaching four [Ru II(bipy)2Cl] groups to the pyridyl substituents of meso-tetra(4-pyridyl)porphyrin and its metallated derivatives. These compounds display a rich electrochemistry and versatile catalytic, electrocatalytic and photochemical properties, associated with the ruthenium

14. Supramolecular properties of polynuclear porphyrins / Propriedades supramoleculares de porfirinas polinucleares
A síntese e a caracterização de uma série de porfirinas polinucleares, por meio de análise elementar, espectroscopia eletrônica e Raman ressonante, voltametria cíclica e espectroeletroquímica, são apresentadas nesta tese. Estas supermoléculas foram obtidas pela coordenação de quatro grupos Ru(edta)- ou Ru(bipY)2Cl+ aos resíduos piridínicos das

15. Synthesis and properties of new polymetalated porphyrins / Sintese e propriedades de novas porfirinas polimetaladas
Metalloporphyrins containing peripheral meta l complexes attached to the macrocyclic ring can exhibit an interesting supramolecular chemistry, modeling , for instance, photosynthetic systems in their ability to undergo intramolecular photocatalyzed electron transfer; and cytochrome-c oxidase , by acting as multielectron redox catalysts in the reduction of mo

16. Extending supramolecular fullerene-porphyrin chemistry to pillared metal-organic frameworks
Porphyrins and fullerenes are spontaneously attracted to each other. This supramolecular recognition element can be exploited to produce ordered arrays of interleaved porphyrins and fullerenes. C60⋅H2TpyP⋅Pb(NO3)2⋅1.5TCE (H2TpyP = tetra-4-pyridylporphyrin; TCE = 1,1,2,2-tetrachloroethane) crystallizes in the tetragonal P4/n space group and the structur

17. Designing supramolecular porphyrin arrays that self-organize into nanoscale optical and magnetic materials
Tessellation of nine free-base porphyrins into a 3 × 3 array is accomplished by the self-assembly of 21 molecular entities of four different kinds, one central, four corner, and four side porphyrins with 12 trans Pd(II) complexes, by specifically designed and targeted intermolecular interactions. Strikingly, the self-assembly of 30 components into a metallo
