Book Description
The first book to didactically illustrate this particular, prominent class of supramolecular building-blocks covers topics ranging from terpyridine syntheses, via their chemistry and properties, supramolecular structures, and multinuclear metal complexes, right up to functionalized polymers, 3D-architectures, and surfaces. Invaluable for students and lecturers in chemistry and biochemistry, materials scientists, as well as polymer, complex and physicochemists.

Book Description
In recent years, the utilization of terpyridines both in macromolecular structure assembly and device chemistry has exploded, enabling, for example, supramolecular polymer architectures with switchable chemical and physical properties as well as novel functional materials for optoelectronic applications such as light-emitting diodes and solar cells. Further applications include the usage of terpyridines and their metal complexes as catalysts for asymmetric organic reactions and, in a biological context, as anti-tumor agents or biolabels. This book covers terpyridine-based materials topics ranging from syntheses, chemistry, and multinuclear metal complexes, right up to functionalized polymers, 3D-architectures, and surfaces. Aimed at materials scientists, (in)organic chemists, polymer chemists, complex chemists, physical chemists, biochemists, and libraries.

Book Description
"Highly ordered, regularly repeating molecular architectures, constructed via self-assembly techniques, have gained importance over the last three decades due to their potential utilitarian applications. A key construction strategy has relied on the synthesis of specific building blocks capable of forming 'higher-ordered' stable structures that have useful properties that can be used as molecular and supramolecular devices. To this end, mono and bis(terpyridine) ligands have been widely used because of their well known photochemical and electronic properties, as well as their ability to facilitate directed, metal-mediated self-assembly. However, limited accessibility to unsymmetrically functionalized terpyridines has restricted their potential use in the construction of more complex infrastructures. For this purpose, methyl-, methoxy-carbonyl- and cyano-substitution patterns on the 4,4"--Positions of 4'-arylterpyridine were chosen since these functionalities afforded simple routes to a variety of useful substituted building blocks for higher-ordered supramacromolecular architectures. Single crystal X-ray studies of these terpyridines revealed that molecules of the diester terpyridine (approximately coplanar) are stacked by the overlap of the central pyridine rings in consecutive layers with mean interplanar distances of 3.4 Å (pi - pi interactions) in the solid state. Moreover, functionalized bis(terpyridine) ligands were achieved via the Kröhnke method and Pd(0) coupling strategy using either 1,3-toluenylbisboronic acid or 1,3-diethynyltoluene with meta- or para-I or Br-phenylterpyridines. A dinuclear tetracationic Fe(II) complex was prepared via metal-directed self-assembly. The chair-like molecular architecture was primarily characterized by X-ray crystallography, mass spectroscopy (ESI-MS), as well as 1H NMR, UV-vis, and CV experiments. Crystal packing of this metallomacrocycle revealed that it formed channels that encapsulated water and MeCN. The low temperature 1H NMR studies suggested that tpy-Fe-tpy moieties in the dimer were interlocked and resembled a spur gear relationship. Surprisingly, dinuclear and trinuclear metallomacrocycles were formed when 1,3-bis(2,2';6',2"-terpyridine-4'-phen-3-ylethynyl)toluene was treated with equimolar amount of Ru(II) that was confirmed by MALDI-TOF mass and NMR spectroscopy. The construction of a heteronuclear (Ru4Fe2) hexameric metallomacrocycle with methyl- and carbonyl-functionalized bis(terpyridyl) moieties was achieves by Pd(0) coupling strategy for potential solar cell applications and supramolecular aggregation of the resulting hexamers through H-bonding. Carboxylic acid functionalized mono- and dinuclear homo- and heteroleptic Ru(II) percursors were also prepared for the same purposes. The single crystal X-ray structure of a homoleptic Ru(II) complex with tetra-ethoxycarbonyl and di(iodo) groups revealed short iodo-carbonyl interactions."--abstract.
