  "abstract": "We report the synthesis and structural characterization of free-standing, highly crystalline ReSe2 nanotubes, the first phase-pure quasi-1D nanostructure to combine a triclinic lattice with wellaligned walls parallel to the tubular axis. The nanotubes were obtained template-free by direct selenidation of ReO3 powder, and characterized by high-resolution imaging, electron di raction, and low-loss electron energy-loss spectroscopy. The 4D-STEM dataset decoded the complex di raction patterns of the triclinic lattice and enabled direct evaluation of the (multi)chirality of individual layers, yielding a workflow transferable to low-symmetry nanotubes. Spectroscopy revealed band edges consistent with bulk ReSe2 and with additional geometry-related subgap features. This preliminary report can open various research avenues e.g., a geometric route to the bulk photovoltaic e ect, or strain-modified optoelectronic properties. Ultrathin nanotubes are expected to enhance symmetry breaking due to curvature strain, resulting in unique band edge properties, while large-diameter nanotubes can support cavity modes, including whispering-gallerytype cavity modes and exciton-polariton phenomena. Additionally, the anisotropic lattice may enable polarization-selective infrared photodetection.",
