Modifying or functionalizing transition metal dichalcogenides (TMDs) allows their properties to be altered and controlled. Now, non-defect-mediated covalent functionalization of single-layer semiconducting TMDs such as MoS2, WS2 and MoSe2 has been demonstrated by reacting them with organohalides, utilizing the excess charge in the 1T metallic phase.
