Summary: In this work, a theoretical study on a series of two-dimensional tetragonal transition metal chalcogenide monolayers is reported. The study reveals that several of these monolayers exhibit semiconductor behavior, with CdX monolayers demonstrating higher efficiency in sunlight harvesting compared to ZnX monolayers. Additionally, a series of tetragonal KnMX monolayers with moderate band gaps are identified. The electronic transport properties of these monolayers were also investigated. The findings suggest that these novel tetragonal transition metal chalcogenide monolayers have great potential in nanoscale devices, energy storage, and conversion applications.

Summary: The study demonstrates selective C-H activation in the 2-position of pyridine and quinoline with Rh and Ir complexes, resulting in a 2-pyridyl bridging the transition metal and the boron center. Different ligands on the transition metal lead to isomerism derived from the 2-pyridyl fragment connecting via B-N/C-M or B-C/N-M bonds. The strength of the M-C(pyridyl) bond and the nature of the ligand trans to it play key roles in determining the relative M-C/M-N isomer favorability.
