The D. C. Conductivities of Some N-Salicylideneanilines

Abstract A good deal of spectroscopic and structural data are now available on crystalline N-salicylideneanilines. The crystals fall into two groups which are markedly different in both molecular and crystal structures, on the one hand, and in photochemical and spectroscopic properties, on the other. It was considered that these differences should be reflected in a difference in the conduction characteristics of the two groups. A number of members of each group were selected for this study. Conductivity measurements were performed on single crystals in different crystallographic directions. In general, all crystals studied were found to have similar specific resistivities and activation energies for conduction. However, in one case appreciably lower values of these properties were observed. This is believed to be due to suitable orientation of the molecules with respect to the crystal faces to which the electrodes were attached. Overlap calculations for this system are described in an Appendix, and the fa...
