Titanium dioxide (TiO2) nanoparticle films have been used as a conducting support for the
immobilisation of alanine-appended perylene bisimides (PBI-A) via dip-coating and carboxylate
chemisorption. The solvent- and concentration-dependent supramolecular structures of aggregated
PBI-A were successfully translated onto the TiO2 electrodes, providing a method to control PBI-A
assembly on a surface suitable for multiple functionalities. Electron microscopy revealed the extent of
aggregation on the surface, and how this affects electrochemical properties. The films showed
electrochemical reversibility by cyclic voltammetry, and preliminary electrochromic studies show that
three colour states could be accessed. Strategies to improve the overall device performance are
discussed
