“…X-ray diffraction analysis of a single crystal of macrocycle 4 was performed at 100 K on a STOE IPDS-II diffractometer (STOE, Darmstadt, Germany) equipped with a graphite-monochromated radiation source (λ = 0.71073 Å) and an image plate detection system. A crystal mounted on a fine Initial attempts to utilize functionalized macrocycles 1-4 in a complexes-as-ligands approach [51,52] for further metal coordination were frustrated by their rather poor solubilities and their sensitivity towards even mildly Lewis-acidic and oxophilic cations like Zn 2+ or Cu 2+ . Thus, addition of zinc(II) or copper(II) salts to complexes 1 and 2 led to rapid decomposition as indicated by a colour change to brown, the deposition of brownish solids, and the loss of the Ru(CO) stretches in the solution phase and these solid deposits.…”

Tetraruthenium Metallamacrocycles with Potentially Coordinating Appended Functionalities

We present four new tetraruthenium macrocycles built from two 1,4-divinylphenylene diruthenium and two isophthalic acid building blocks with peripheral, potentially mono- or tridentate donor functions attached to the isophthalic linkers. These macrocycles are characterized by multinuclear NMR spectroscopy, mass spectrometry and, in the case of the thioacetyl-appended complex 4, by X-ray crystallography. Cyclic and square wave voltammetry establish that the macrocycles can be oxidized in four consecutive redox steps that come as two pairs of two closely spaced one-electron waves. Spectroscopic changes observed during IR and UV/Vis/NIR spectroelectrochemical experiments (NIR = near infrared) show that the isophthalate linkers insulate the electroactive divinylphenylene diruthenium moieties against each other. The macrocycles exhibit nevertheless pronounced polyelectrochromism with highly intense absorptions in the Vis (2+/4+ states) and the NIR (2+ states) with extinction coefficients of up to >100,000 M−1·cm−1. The strong absorptivity enhancement with respect to the individual divinylphenylene diruthenium building blocks is attributed to conformational restrictions imposed by the macrocycle backbone. Moreover, the di- and tetracations of these macrocycles are paramagnetic as revealed by EPR spectroscopy.

“…A metalloligand can be defined as a coordination complex offering one or more binding sites which can coordinate to the secondary metal ions for the construction of the supramolecular architectures [57–60] . The association of a metal ion with an organic ligand induces structural rigidity in the resultant metalloligand [61,62] . Such an induced rigidity of a metalloligand orients the appended peripheral functional groups to the limited orientations [60,62,63] .…”

This article discusses the design principles and strategies and the structural outcome of various supramolecular architectures constructed by utilizing well-defined coordination complexes as the metalloligands. We have included selected examples of metalloligands, offering either pyridyl or arylcarboxylic acid groups as the appended functional groups, for illustrating the construction of their supramolecular architectures. Both geometrical position and the number of the appended functional groups emerging from a metalloligand were found to critically regulate the structural aspects and dimensionality of the resultant material. The article concludes by delineating the structure-directing lessions as well as the potential applications of the metalloligand-based supramolecular architectures for the generation of next-level materials.
