Thermal stabilities of nanocomposites: mono- or binuclear Cu complexes intercalated or immobilised in/on siliceous materials

摘要

Various copper(II) complexes as guests were immobilised among the layers ofudmontmorillonite or on silica gel as hosts. Anchoring took place through hydrogen bondsudand ion exchange for montmorillonite, while the forces of interaction were either hydrogenudbonding or covalent bonds for the copper complex–silica gel nanohybrids. Theudthermal stabilities of these substances were studied under oxidizing atmosphere and itudwas found that anchoring increased the durability of the host-guest complexes relativeudto the host-free ones.
