Application
Triethylene glycol monomethyl ether (TEGME) was used in the following studies:
- To study the structural and thermosensitive properties of phosphazene derivatives having glycol and amino acids groups.
- Synthesis of amphiphilic o-phenylene ethylene oligomers.
- Preparation of pegylated zinc(II) phthalocyanines.
- Modification of 2-OH positions in cyclodextrin thioethers, which are used for transport of hydrophobic drugs.
- Functionalizing polymethacrylic acid (PMMA), hence increasing inhibition in crack generation in TEGMA-PMMA compared to unmodified PMMA electrodes.
- Preparation of difunctionalized ionic liquids (ILs).
- As terminal groups for cationic dendrons, which was further used to encapsulate an inorganic polyanionic cluster.

A series of cationic dendrons bearing triethylene glycol monomethyl ether terminal groups of different generations have been synthesized and used to encapsulate an inorganic polyanionic cluster [K(12.5)Na(1.5)(NaP5W30O110)] through electrostatic interactions. The resulting dendritic cation-encapsulated polyoxometalate (POM) complexes, cluster-dendrimers, are soluble
