  • The lipophilic triazole ligand 1 (C12OC3Trz) has been designed such that an ether linkage exists in the alkyl chain moiety. This flexible ether linkage enhances the solubility of various complexes of this ligand (including [CoII(1)3]Cl2 and [FeII(1)3]Cl2) in organic media and also improves the packing efficiency of the alkyl chains. Such lipophilic modifications of 1D coordination systems can result in dynamic structural transformations leading to unique solution properties, including heat-set gel-like networks, guest-induced structural changes, electrochemical transformations and spin crossover state switching.

  • A number of amphiphilic N-isopropylacrylamide (NIPAAm) oligomers and polymers with a S-1-dodecyl-S′-trithiocarbonate (DTC) and an amino terminal group has been designed. The electrostatic interactions between the amine segments and the anionic metal cyanide complexes have a significant role in the morphology and thermoresponsiveness of the hybrids. The hybrids of PNIPAAms and metal complexes can lead not only to nanostructures in water but also to cylindrical aggregates (or spherical aggregates) assembled in rod, square and sheet structures.
