We discovered a method for growing vertically aligned bundles of Mo6S9-xIx (4.5< x < 6) nanowires perpendicular with respect to the substrate. In this efficient method, one step synthesis direct from molybdenum, sulphur and iodine in the temperature gradient conditions is used. The bundles with similar lengths and diameters could be grown on quartz or conductive materials like molybdenum foil at the temperature around 1040 K. This material could be potentially used for some applications like as building blocks in nanodevices.

Charge transport measurements on flexible Mo6S3I6 molecular wires of different diameters are best described by tunnelling through Tomonaga-Luttinger liquid segments, which is in some cases modified by environmental Coulomb blockade arising from deformations or imperfections. The unique S-bonding chemistry of Mo6S3I6 wires and gold nanoparticles enables self-assembly of large molecular-scale inorganic networks. The topological characteristics of networks indicate an intrinsic tendency to self-organize into a scale-invariant critical state.

Mo6S3I6 nanowire networks of interest are found to change their resistance in response to the presence of analyte vapors. The vapor sensing behavior is quantitatively described very well phenomenologically in terms of the concentration of adsorbed analyte molecules in the contact tunneling junctions, and an expression is derived for the dynamics and sensor resistance in terms of analyte vapor pressure. The time response of the sensor is observed to follow simple adsorption-desorption kinetics. The network sensor shows very clear selectivity.

Charge transport measurements on flexible Mo6S3I6 (MoSI) nanowires with different diameters in highly imperfect two-terminal circuits reveal systematic power-law behavior of the conductivity sigma(T,V) as a function of temperature and voltage. On the basis of measurements on a number of circuits we conclude that the behavior in thin wires can be most convincingly described by tunneling through Tomonaga-Luttinger liquid segments of MoSI wire, which is in some cases modified by environmental Coulomb blockade.

the MoS2 nanotube hybrids represent a family of nanomaterials, where nanotubes serve as nanoreactors and in some cases also as nanocontainers of MoS2 fullerenelike particles, which have in situ grown in a confined geometry of nanotubes. A simple temperature control of morphology, size, and inner structure of nanohybrids leads to a selective morphology.
