“…19 In contrast, cyclic voltammetry on the iron(III) complexes 7 revealed a reversible reduction of the metal center at -0.55 V (vs. SCE; Table 1). 20 The reduction potentials for all iron(III) complexes are essentially identical 65 and indicate that functionalization of the phenolate unit does not alter the electronic properties of the metal center. Obviously, the electronic activity of the metal center is not affected by variation of the structurally directing hydrophobic tails.…”

“…18 Reaction with CoCl 2 and subsequent standing in air gave the corresponding cobalt(III) complexes 5. Acceleration of metal oxidation by 20 saturating the reaction mixture with O 2 lowered the yields of 5 substantially, suggesting that initial metal coordination requires a cobalt(II) center. The non-coordinating counter anion in 5 was readily displacable because of the high solubility of 5 in organic solvents.…”

“…In addition a new maximum at 346 nm is observed, perhaps due to a ligand centered process. 22 Self-assembly 20 The potential of the functionalized complexes to form organized structures was probed at the air-water interface and on highly ordered pyrolytic graphite (HOPG).

“…1 A classic 20 example for such enhanced activity due to cooperation is the spin transition in spin-labile complexes. 2,3 Synchronized spin crossover typically results in abrupt transitions, often accompanied by a hysteresis, while non-cooperative transitions are gradual and hence much less attractive.…”

Organization of spin- and redox-labile metal centers into Langmuir and Langmuir–Blodgett films

New sal 2 (trien) ligands that contain alkoxy substituents of various length in meta position of the salicyl entities were coordinated to electronically and magnetically active iron(III) and cobalt(III) centers. The electrochemical and spectroscopic properties of these amphiphilic complexes are 10 virtually unaffected upon alteration of the alkoxy substituents, thus providing a system in which the physical behavior and the metal-centered chemical activity can be tailored independently. The amphiphilic character has been exploited for preparing Langmuir monolayers at the air-water interface and for constructing Langmuir-Blodgett films, hence allowing for hierarchical assembling of electronically and magnetically active systems. While Langmuir films were stable, transfer onto 15 solid supports was limited, which restricted the magnetic analysis of the Langmuir-Blodgett assemblies.
