A supramolecular approach to lithium ion solvation at nanostructured dye sensitised inorganic/organic heterojunctions

A novel arylamine based hole transporting material ( HTM) with tetraethylene glycol ( TEG) side groups is reported. Lithium ions solubilised by the TEG groups are employed to modulate interfacial electron transfer reactions at a dye sensitised TiO2/ HTM interface.
