β¦ Synopsis
Photocurrent peaks in the near-infrared (NIR) are observed with ZnTPP thin-film electrodes in solutions. The peak positions compare well with those of the synergism spectrum for the AI/ZnTPP/Au dry cell although no NIR photocurrent is seen in the action spectrum of the dry cell. It is speculated that the magnitude of the NIR photoresponse attributable to a trace of ZnTPP photoproducts depends on the position of the LUMO levels of the impurity relative to the Fermi level of the ZnTPP solid at the metal/ZnTPP or solution/ZnTPP interface.

A near-infrared (NIR) -absorbing cyanine dye was used as a probe for in situ characterization of Nafion thin films. This NIR dye was very sensitive to changes in the hydrophobicity of the environment and proved to be very suitable for probing the Nafion coatings, which involve a two-phase structure
The apparent discrepancy between pseudocapacitances measured with different techniques which is observed for thin poly(4-vinylpyridine) coatings containing IrCIi-'3-on gold electrodes is discussed. The phenomenon is explained by the establishment of slow relaxation processes in the charge transport
