Special Issue Information

Dear Colleagues,

Low-dimensional nanomaterials, including 0D nanoparticles, 1D nanotubes, and 2D nanosheets, exhibit fascinating physical and chemical properties that differ significantly from their 3D bulk counterparts. This makes them a cornerstone of modern nanoscience and a critical area of research, with an enhanced understanding of their photophysical and electronic properties required in order to advance fundamental nanoscience and promote future innovations in optoelectronics and electronics.

This Special Issue aims to showcase experimental and theoretical advances in the chemistry and physics of low-dimensional materials. We welcome original research and comprehensive review articles that explore the photophysical and electronic properties of these materials, with a focus on the following topics:

  • Luminescent and nonlinear optical materials;
  • Electronic properties and states;
  • Optoelectronic and electronic device fabrication;
  • Advanced characterization techniques.

We are particularly interested in submissions that address a diverse range of materials, including the following:

  • Inorganic nanomaterials (e.g., metals, metal oxides, metal sulfides);
  • Organic nanomaterials (e.g., covalent organic frameworks, polymers, supramolecular assemblies);
  • Inorganic-organic hybrid materials (e.g., coordination polymers, metal-organic frameworks, nanocomposites).

We invite you to contribute novel research to this Special Issue and share your work with the global scientific community.

We look forward to your valuable contributions.

Nickelladithiolene nanosheet, Ni3BHT, is a two-dimensional material composed of nickel ions and benzenehexathiol (BHT). Ni3BHT has attracted considerable attention owing to its electrical conductivity. Although conventional Ni3BHT is obtained as a solid film or powder, recent studies have explored methods for handling Ni3BHT as a liquid ink, which facilitates industrial applications. One such method involves adding a modulator ligand to control the morphology of Ni3BHT. In this study, we developed a novel modulator ligand, 4,5-dihexylbenzene-1,2-dithiol (CL1), which afforded a more stable and concentrated Ni3BHT dispersion than those previously reported. Further investigations suggest that CL1 is incorporated not only at the termini but also within the interior of the Ni3BHT nanoflakes, based on the consistent interpretation of spectroscopic and morphological data, in the dispersion via the addition of an adequate amount of a modulator. The application of the Ni3BHT dispersion as a conductive ink was demonstrated. The Ni3BHT ink exhibited the highest electrical conductivity and colloidal stability at a CL1/BHT ratio of 0.3. These findings pave the way for potential applications of Ni3BHT in various industries. Full article
