Salen‐Based Amphiphiles: Directing Self‐Assembly in Water by Metal Complexation

“…Unlike Cu and Ni, the metal centers of the Co,F e, and Mn salen amphiphiles may coordinate water as an external ligand. [61][62][63] Water coordination should lead to ah igher hydrophilic character (a 0 ) resulting in ad ecrease of the CPP as is reflected in the structural change from cubic to lamellar and eventually micellar aggregates for Mn complexes.Atthe same time,the hydrophobic volume is reduced, as the metal participates in hydrating the amphiphile.T he generation of an octahedral complex, also sterically different from the square planar complexes of Cu and Ni, would cause asignificant change in CPP.O verall, the hydration of the amphiphile is therefore expected to drive the self-assembly process from inverted micelles (CPP > 1f or L1-Cu and L1-Ni)t ob ilayers ( 1 = 2 < CPP < 1f or L1-Co and L1-Fe)a nd even micelles (CPP < 1 = 2 for L1-Mn).…”

‘Oxygen-Consuming Complexes’–Catalytic Effects of Iron–Salen Complexes with Dioxygen

“…According to the literature, there are many examples of the synthesis of the complex of iron(III) salen [20,47,64,65,72], and only a few examples of the synthesis of the iron(II) salen complex [73]. The complex [(salen)Fe III ] + , in most of those articles, was synthesized according to the procedure of Matsushita et al (1982) according to which ferric chloride and the salen ligand in a 1:1 molar ratio were dissolved in absolute CH 3 OH, and the resulting mixture was heated to reflux under an inert gas atmosphere for about 2.5 h. Solid [(salen)Fe III ]Cl was isolated by filtration and then used for catalytic purposes [74].…”
