“…This method produced nanoribbons with widths of approximately 30 to 80 nm which were then subsequently exfoliated further by mechanical means. Further colloidal dispersions have been achieved for TaS3 in MeCN and DMSO 142 , and for NbS3 and NbSe3. 143,144 Figure 5 …”

The isolation of graphene and transition metal dichalcongenides has opened a veritable world to a great number of layered materials which can be exfoliated, manipulated, and stacked or combined at will. With continued explorations expanding to include other layered materials with unique attributes, it is becoming clear that no one material will fill all the post-silicon era requirements. Here we review the properties and applications of layered, quasi-one dimensional transition metal trichalcogenides (TMTCs) as novel materials for next generation electronics and optoelectronics. The TMTCs present a unique chain-like structure which gives the materials their quasi-one dimensional properties such as high anisotropy ratios in conductivity and linear dichroism. The range of band gaps spanned by this class of materials (0.2 eV-2 eV) makes them suitable for a wide variety of applications including field-effect transistors, infrared, visible and ultraviolet photodetectors, and unique applications related to their anisotropic properties which opens another degree of freedom in the development of next generation electronics. In this review we survey the historical development of these remarkable materials with an emphasis on the recent activity generated by the isolation and characterization of atomically thin titanium trisulfide (TiS3).

“…The discovery of the unique graphene properties 1 has triggered significant growth in research on nanosheets, nanoribbons and nanorods of other layered or chain-structured inorganic compounds. In particular, nanosized counterparts of hexagonal boron nitride, transition metal dichalcogenides, trichalcogenides and tetrachalcogenides [2][3][4][5][6][7][8] have been the focus of intense research. The structures of all these compounds are characterized by weak van der Waals bonding between covalently assembled layers (or chains), allowing the exfoliation of the compounds to give nanosheets as thin as a single layer.…”

Similarly to transition metal dichalcogenides akin to MoS2, transition metal polysulfides like tri‐ and tetrachalcogenide materials are nowadays incorporated into catalysts and composites used for energy conversion and storage, etc. However, polysulfide structures feature SS units, which make them strikingly different from the widely known MoS2 and other dichalcogenides. At the same time, their surface chemistry and its relation to properties are very little studied. Reported here is one of the first observations on the oxidizing properties of disulfide bridges (SS)2− forming surfaces in polysulfide crystals. Upon interaction with silver salts or silver nanoparticles, MoS2 acts as most supports, that is, it stabilizes metallic Ag at its surface; in contrast, curiously, patronite VS4 and NbS3 stabilize Ag2S nanoparticles under identical reducing conditions. The Ag/MoS2, Ag2S/NbS3, and Ag2S/VS4 samples are characterized with X‐ray diffraction, transmission electron microscopy, and X‐ray photoelectron spectroscopy. Apparently, the unexpected formation of Ag2S is due to complex redox processes involving disulfide fragments –S–S– of nanorods VS4 or nanoribbons NbS3, which are absent in MoS2 nanosheets. This result is important for fundamental understanding of the properties of sulfur‐rich surfaces and also for contributing to the number of available synthetic paths toward Ag2S nanoparticles.
