Abstract: | |||||
Transition metal directed self-assembly can be utilised to design and form metallosupramolecular
assemblies such as coordination polymers or polyhedra. Examples have
shown these materials to possess useful properties such as porosity or catalytic
behaviour allowing them to be used as functional materials. The design and
investigation of new metallo-supramolecular materials is of great interest in
supramolecular chemistry and crystal engineering with the goal of future applications in
areas such as nanoscale devices, gas storage and molecular machinery.
Two groups of tripodal ligands with donor atom functionality have been successfully
synthesised and their coordination ability investigated. One group of ligands are hosttype
'curved' ligands based on the molecule cyclotriveratrylene (CTV) and the· other
group are planar in nature. Both discrete and infinite entities have been formed
including a rare 3-D triply interlocked [2]-catenane from the ligand tris(4-[4-methyl2,2'-
bipyridyl]methyl)CTG with Zn(N03)2 and Co(N03h. A number of the ligands
have shown to act as Low Molecular Weight Gelators (LMWG's) to form both organoand
metallo-LMWG's that possess a mixture of thermo, mechano and chemo
reversibility.
