Two new series of guanidine–pyridine ligands have been synthesised by the reaction of various chloroformamidinium chlorides with 8-aminoquinoline or 2-picolylamine. The ligands were treated with either zinc chloride or zinc acetate to prepare the c

We mechanically exfoliate mono- and few-layers of the transition metal dichalcogenides molybdenum disulfide, molybdenum diselenide, and tungsten diselenide. The exact number of layers is unambiguously determined by atomic force microscopy and high-re
