trans‐1,2‐Bis(N‐methylimidazol‐2‐yl)ethylene: Towards Building Blocks for 2D Fabrics and MML‐Type 1D Molecular Strands

Battlement-shaped 1D coordination polymer based on a bis(N-methylimidazole-2-yl)butadiyne ligand

“…6a,11 Similar to related compounds, 12 the absorption spectrum ( Fig. 2) of bmib (7) gives rise to vibronic transitions in the 280 to 350 nm range with maxima at 292, 308, 328, and 350 nm with an energetic spacing of 2000 cm −1 . These are assigned to the triple bond centered π-π* excited state.…”

1D Chains of Diruthenium Tetracarbonyl Sawhorse Complexes

“…General Remarks: The ligand trans-bie [6] and [Ru(μ-OAc)(CO) 2 ] n [26] were prepared by methods described in the literature. All other chemicals were used as purchased.…”

“…This polymer showed interesting properties towards metal-ligand-derived semiconducting nanowires. [6] During these studies, particularly with the divalent [Ru 2 (μ-OAc) 4 ] paddlewheel unit, we became aware of the related but monovalent dinuclear ruthenium(I) building block [Ru 2 (μ-OAc) 2 (CO) 4 ], which may also be suitable for the formation of 1D chains.…”

“…2 (μ-OAc) 4 }(μ-trans-bie)] n , [6,7] in which paddlewheel building blocks of various metal(II) acetates (M = Cu, Cr, Mo, Rh, Ru) are chained together by the trans-bie ligand (Scheme 1). Scheme 1.…”

Self‐Assembly of a Mononuclear [FeIII(L)(EtOH)2] Complex Bearing an n‐Dodecyl Chain on Solid Highly Oriented Pyrolytic Graphite Surfaces

“…[4][5][6][7][8] Generally, CITS measurements provide direct information about the local conductance at these energies and, indeed, we have successfully applied this technique to a range of metal complexes. [5][6][7][8][9] Earlier studies by us showed that ferric wheels derived from poly-alcoholato ligands substituted with octadecyl alkyl side arms form well-ordered arrays upon adsorption on highly oriented pyrolytic graphite (HOPG) surfaces. [10] Long-alkyl-chain-substituted complexes were employed to increase van der Waals interactions between molecules and the substrate to stabilize molecular aggregates on the surface.…”
