Amphiphilic Iron(II) and Nickel(II) Complexes Based on Alkylated Diazaoxa‐ and Triazacyclononane

Abstract

It is known that including a metal into a micellar solution enhances both the colour and catalytic potential of such systems. This fact is well exemplified by the broad use of surfactant species as phase-transfer catalysts. In the present work, we report our studies concerning the aggregation properties of a series of iron and nickel-based triazacyclononane metalloamphiphiles. Upon multiple alkylation of the triazamacro-

Proton switching of polarity in metalloamphiphile crystals

“…[6][7][8] Amphiphiles derived from metal ion complexes are of interest because of the properties, both electronic and magnetic, which the metal ion adds to those of amphiphilicity and the associated overall polarity. [9][10][11] Macrobicyclic (cage) amine complex units make a useful amphiphile head group [12][13][14] because of the variety of metal ions which may be bound in a kinetically inert entity and, in the course of studies of simple amphiphiles derived from cage amine complexes, we have obtained the present evidence of the subtlety of the factors influencing their assembly into polar arrays. This is of particular interest due to the potential benefits of incorporating coordination complexes into NLO materials.…”

The Preparation, Solution and Mesophase Behaviour of Surfactant Complexes of Cobalt(III)

“…Major contributions in this area have been reported by Fallis, Griffiths and co‐workers9 studying amphiphilic macrocycles and their metal complexes, while with Bowers, we have studied surfactant complexes of ruthenium(II) by small‐angle neutron scattering10 and by neutron reflectivity 11. More recently, Dominguez‐Gutiérrez et al have investigated inverse structures of tetraalkylated ruthenium surfactants12 as well as surfactant derivatives of Ni II and Fe II 13. Other contributions are collected as reference 14…”

Cyclononanes: The extensive chemistry of fundamentally simple ligands

“…c c e p t e d M a n u s c r i p t proposed that differences in geometries of the complexes as well as the nature of the polar head, that is the differences between the N 3 and N 2 O donors in the two cyclononane ligands, contributed to the differences[253].The diazaoxa macrocycle 2,5-diaza-12-oxa[12.4.01,13 .08,11 ]tricycloseptadecane has been prepared by reaction of ethane-1,2-diamine with cyclohexene oxide and subsequent ring closure[254]. Reaction of the ligand with K 2 PdCl 4 resulted in isolation of the complex characterised as [Pd(L)(OH 2 ) 2 ](PdCl 4 )[254].…”
