Paramagnetic Properties

An alkali-polyketene-enolate was made from polyketene by using aqueous bases MOH (M = Li, Na, K, Rb, Cs). The structure is proposed on the basis of IR and 13C NMR spectra, the paramagnetic properties were investigated by EPR spectroscopy. AC conductivity measurements show a maximum conductivity of 10-2 S cm- 1 (at 115 °C), where marked ionic participation is expected. Doping of the polyacetylene backbone with iodine gives no increase of conductivity; CV measurements indicate the presence of triiodide anions.

Lithium Ion Conductivity

Phase studies and ac-conductivity measurements were carried out in the compositions M0.8In0.2Li0.2P2O7 [MILP] (M=Sn, Zr, Ti). The bulk conductivities were of the order of ~10-5 Scm-1 at 623 K and higher in the order of TiILP≥ZrILP>SnILP. The activation energies, as expected, became lower in the order of ZrILP<TiILP<SnILP with increasing size of the bottleneck windows for hopping of the Li ions. The order of TiILP≥ZrILP>SnILP in bulk conductivities were not correlated with that of the activation energies probably because of the impureness of the ZrILP sample.
