Functionalization and Structural Evolution of Conducting Quasi-One-Dimensional Chevrel-Type Telluride Nanocrystals.

Finally, we evaluated the electrical transport properties of the resulting hybrid surface-functionalized nanocrystals, which showed a trend in ensemble conductivity as a function of both the alkyl chain length of −NR 4 + and the average grain size within each sample. 2 Experimental Section 2.1 Solid-State Synthesis of Bulk In 2 Mo 6 Te 6 Crystals Elemental precursors of In (99.9%, Strem Chemicals Inc.), Mo (99.5%, Strem Chemicals Inc.), and Te (99.9%, Strem Chemicals Inc.) were used as purchased and were mixed in appropriate stoichiometric ratios and placed in a quartz ampule evacuated to 45 mTorr.
