Abstract

Dimethyl sulfoxide (DMSO) solutions of the inorganic polymer (LiMo3Se3)n are cast or spin coated to form lustrous metallic films after heating in vacuo. Transmission electron microscopy (TEM), ultrahigh-vacuum scanning TEM (UHV-STEM), X-ray diffraction, and SEM microprobe analysis confirm that the films consist of locally ordered linear chains and chain bundles of (LiMo3Se3)n. Thick (≥1µm) free-standing foillike films display thermally activated conductivity and a low resistivity of 5 x 10-3 Ω cm-1 at 23 °C. Highly oriented thin films (<1µm), prepared by the flowing of solutions, display order over 160µm, as confirmed by absorbance polarized light microscopy.
