9. 2 area, 3 s) the absorbance at 610 nm increased by 0.085 absorbance units owing to formation of the radical cation of the viologen component. Using the extinction coefficient for the radical cation of the viologen component as given in ref. 10, it is estimated that a further 14% of the viologen components are reduced. The combined percentage, 34%, is in excellent agreement with that observed prior to irradiation at an applied potential of -0.60 V (32%).6

18. -1, supplied by Glastron) was mounted over the working electrode and sealed using a proprietary adhesive supplied by Donnelly Mirrors (Ireland) Ltd. The above adhesive, which contained 80 μm polystyrene beads to maintain a constant separation between the working and counter electrodes, was cured at 130 °C for 1 h. One corner of the device was kept free of adhesive to permit subsequent introduction, by vacuum back filling under argon, of the following electrolyte: acetonitrileethanol (73:30, v/v), TBAP (O.lOmoldnT3) and TEOA (0.05 mol dirT3). Finally, this opening was sealed using proprietary UV rapid-cure adhesive, again supplied by Donnelly Mirrors (Ireland) Ltd. The device was connected to a Thompson Electrochem Ministat 251, configured to act as a precision voltage source.
