Ruthenium pyroelectric effect

The results, for an alternate layer structure of a ruthenium complex and behenic acid, are shown in figure 3. The structure of the ruthenium complex is shown schematically in figure 4 [7] When normalisation is performed, to take account of the dilution of dipole moment due to the buffer layers, it is found that the pyroelectric coefficient is independent of the number of active layers. This is the result to be expected, if the effect observed is true pyroelectricity, since the pyroelectric coefficient is dependent only on the number of dipoles per unit volume. Work is still in progress to attempt to isolate the exact mechanism responsible. These results compare favourably with the largest pyroelectric coefficients found in acid/amine LB films, typically 1.3pCm"2K i [7].
