Inclusion of a cobalt tetraazamacrocycle into layered molybdenum disulfide

We report on the intercalation of meso-5, 5, 7, 12,12,14-hexamethyl-1,4,8,11-tetraazacyclotetradecane-1,8-diacetate complexed with Co (III) into layered molybdenum disulfide. This is achieved by using the exfoliation and re-stacking properties of LiMoS 2. The cobalt complex dissolves readily in a wa...

Description
Summary:We report on the intercalation of meso-5, 5, 7, 12,12,14-hexamethyl-1,4,8,11-tetraazacyclotetradecane-1,8-diacetate complexed with Co (III) into layered molybdenum disulfide. This is achieved by using the exfoliation and re-stacking properties of LiMoS 2. The cobalt complex dissolves readily in a water/acetone solvent mixture. Addition of this solution to an aqueous suspension of single MoS 2 layers results in the entrapment of the cobalt macrocycle between the sheets of MoS 2. The resulting intercalate was characterized by powder X-ray diffraction and thermogravimetric analysis.
