“…The electronic absorption spectra in the 200-1100 nm range were obtained in DMF on a Shimadzu UV-1700 UV-Visible spectrophotometer (Firat University, Elazig, Turkey). Magnetic susceptibility were measured at room temperature with MK-1 model Gouy balance (Firat University, Elazig, Turkey) using Hg[Co(SCN) 4 ] as a reference for calibrant. Conductivities of a 10 -3 M solution of the complexes were measured in DMF at 25 o C using a CMD 750 WPA model conductivity meter (Firat University, Elazig, Turkey).…”

“…The electronic spectrum of the Co(II) complex gives two bands 410 and 500 nm. These bands may be assigned to the transitions 4 T 1g (F)(D 4h ; 4 E g ) → 4 T 1g (P)(D 4h ; 4 A 2g ) and 4 T 1g (F)(D 4h ; 4 E g ) → 4 T 1g (P)(D 4h ; 4 E g ), respectively. The positions of these bands suggest a tetragonal environment around Co 2+ ion [38].…”

“…Metal complexes containing diimine ligands such as 1,10-phenanthroline and its derivatives have gained importance because of their versatile roles as building blocks for the synthesis of metallo-dendrimers and as molecular scaffolding for supramolecular assemblies, and in analytical chemistry, catalysis, electrochemistry, ring-opening metathesis polymerization and biochemistry [1][2][3][4][5][6][7][8][9][10].…”

ABSTRACT. In this study, the ligand, 2-p-tolyl-1H-imidazo[4,5-f][1,10]phenanthroline (L) was synthesized by the reaction of 1,10-phenanthroline-5,6-dione with 4-methylbenzaldehyde. The complexes of L were prepared with Co(II), Ni(II) and Cu(II) chlorides. The ligand and its complexes were characterized by IR, UV/VIS, 1 H NMR, TGA, elemental analyses, molar conductivity and magnetic susceptibility. The complexes were proposed to be distorted octahedral geometry. Antibacterial activity of the ligand and its complexes were tested against selected bacteria. The minimum inhibitory concentration (MIC) was determined for the ligand and its complexes.

“…[149][150][151] These characteristics can be very conveniently exploited for the preparation of arrays of modified electrodes. The strategy based on the electropolymerization of halogen substituted aromatic compounds has already been reported in the case of the reductive dimerization of 5-chlorophenanthroline (5-ClPhen) by Fussarydel et al 152 Following this approach, the corresponding porphyrin supermolecular species by attaching four [Ru(5-ClPhen) 2 Cl] + groups to the pyridine N-atoms of H 2 (TPyP) have also been developed. Such species have been called ETRP (electropolymerizable tetraruthenated porphyrins).…”

“…The reduction of the 5-ClPhen ligand induces the elimination of the phenanthroline chloro group as chloride anion and the formation of a radical species 152 which reacts promptly with another radical, forming a dimer in the case of the free ligand. The H 2 (ETRP) species has two of such ligand for each of the four peripheral ruthenium complexes.…”

Neste limiar da era nanotecnológica, o planejamento molecular dos materiais e os estudos de moléculas isoladas estão abrindo imensas possibilidades no emprego de sistemas moleculares em dispositivos eletrônicos e fotônicos, bem como em aplicações tecnológicas baseadas em propriedades de chaveamento ou reconhecimento molecular. Com esse escopo, os químicos inorgânicos em particular, podem aplicar com vantagens as estratégias proporcionadas pela química de coordenação, para construir nanomateriais funcionais que permitam a exploração das propriedades dos centros metálicos e das características dos ligantes presentes. A química de coordenação também oferece recursos eficientes na auto-montagem de nanoestruturas, baseadas na especificidade da interação metal-ligante e nas características estereoquímicas dos complexos. Diversos materiais moleculares gerados a partir de compostos inorgânicos e metal-orgânicos são focalizados neste artigo, com ênfase em novas porfirinas e porfirazinas supramoleculares, clusters e complexos metálicos. Tais sistemas também são enfocados sob o ponto de vista de suas aplicações em catálise, sensores e dispositivos moleculares.At the onset of the nanotechnology age, molecular designing of materials and single molecule studies are opening wide possibilities of using molecular systems in electronic and photonic devices, as well as in technological applications based on molecular switching or molecular recognition. In this sense, inorganic chemists are privileged by the possibility of using the basic strategies of coordination chemistry to build up functional supramolecular materials, conveying the remarkable chemical properties of the metal centers and the characteristics of the ancillary ligands. Coordination chemistry also provides effective self-assembly strategies based on specific metal-ligand affinity and stereochemistry. Several molecular based materials, derived from inorganic and metal-organic compounds are focused on this article, with emphasis on new supramolecular porphyrins and porphyrazines, metal-clusters and metal-polyimine complexes. Such systems are also discussed in terms of their applications in catalysis, sensors and molecular devices.
