'ONE-POT' SYNTHESIS OF 2D, 1D, E 0D NANO CRYSTALS OF TUNGSTEN AND MOLYBDENUM CHALCOGENIDES (WS2,MOS2) FUNCTIONALIZED WITH LONG CHAIN AMINE AND/OR CARBOXYLIC ACID AND/OR THIOL

摘要

The present invention describes a new synthetic strategy that permits to produce 2D 1 D, e OD hybrid organic-inorganic nanocrystals of tungsten/molybdenum chalcogenides. The innovative chemical approach is based on the thermal decomposition of a molecular precursor containing both metal and sulphur, in a mixture of long chain amines and/or fatty acids and/or long chain thiols. By the control of reaction conditions is possible to address the synthesis can be driven towards the formation of nanosystems with different morphologies such as sheets, particles, rods, tubes.
