Lateral size, surface chemistry, and properties are varied in inorganic monolayers based on a transition metal-oxide. A variety of inorganic monolayers with their emergent properties have been studied in recent decades. However, it is not easy to tune the lateral size, surface chemistry, and dispersibility of monolayers by typical synthetic methods. In the present work, a new approach is developed for the simultaneous surface functionalization and exfoliation of the precursor nanocrystals in a nonpolar organic medium. We obtained monolayered nanodots of a titanium oxide less than 5 nm in lateral size with surface functionalization by an alkylamine (C14H29NH2) and dihydroxynaphthalene (DHN) in toluene. The bandgap energy of the monolayers was changed by the lateral size and surface functionalization. The present study suggests versatile potentials of the monolayers with tuned size, surface chemistry, and properties.

Physical Chemistry Chemical Physics

Physical Chemistry Chemical Physics (PCCP) is an international journal co-owned by 19 physical chemistry and physics societies from around the world. This journal publishes original, cutting-edge research in physical chemistry, chemical physics and biophysical chemistry. To be suitable for publication in PCCP, articles must include significant innovation and/or insight into physical chemistry; this is the most important criterion that reviewers and Editors will judge against when evaluating submissions. The journal has a broad scope and welcomes contributions spanning experiment, theory, computation and data science. Topical coverage includes spectroscopy, dynamics, kinetics, statistical mechanics, thermodynamics, electrochemistry, catalysis, surface science, quantum mechanics, quantum computing and machine learning. Interdisciplinary research areas such as polymers and soft matter, materials, nanoscience, energy, surfaces/interfaces, and biophysical chemistry are welcomed if they demonstrate significant innovation and/or insight into physical chemistry. Joined experimental/theoretical studies are particularly appreciated when complementary and based on up-to-date approaches.
