Luminescent gels by self-assembling platinum complexes.

A platinum complex bearing a tetraethylene glycol chain has been designed and its self-assembly properties investigated. In solution, only a yellow phosphorescence of the aggregated species is observed. The complex gives luminescent gels of different colours with DCM and DMF, reaching up to 60% photoluminescence quantum yield.

Responsive supramolecular gels constructed by crown ether based molecular recognition.

Responsive supramolecular gels were constructed from crown ether terminated four-arm star poly(epsilon-caprolactone) (PCL-DB24C8) and dibenzylammonium-terminated two-arm PCL-DBAS (see scheme), exploiting the formation of pseudorotaxane linkages between crown ether and ammonium moieties. The resultant supramolecular gels exhibit thermo- and pH-induced reversible gel-sol transition.

How should multicomponent supramolecular gels be characterised?

Low molecular weight gels, or supramolecular gels, are formed when small molecules self-assemble into fibrous structures. Above a critical concentration, the entanglement and cross-linking of these structures leads to the formation of a self-supporting gel. There are many examples where a single component is used to form such gels. There is however an ever-increasing interest in using multiple ...
