functionalized β-cyclodextrin (β-CD) derivative and tris(3-aminophenyl)phenyl phosphineoxide (TAP). Cloisite Na+ (clay-Na) and the modifiers were used for the preparation of the organoclay containing phosphineoxide (clay-PO) and of the organoclay containing β-cyclodextrin (clay-CD) via ion-exchange reaction. Biobased semi-aromatic polyamide (BPA)/functional clay (clay-PO and clay-CD) nanocomposites subsequently

designed and synthesized for coupling and crosslinking. The three reactive sites of TDA-1 can react with phenol-containing molecules as well as plant viruses in aqueous buffers efficiently. In addition, a new-type azo-linked cage was constructed by the direct reaction of TDA-1 with a triple-phenol molecule and was characterized by X-ray crystallography.

New products having the structure of arylphosphines or of derivatives of arylphosphines with an oxygen or sulphur atom directly bonded to the phosphorus atom, containing perfluoroalkylether chains, characterized in that such chains are bonded to the benzene ring through a non-perfluorinated bridge, and are obtained by a process substantially decreasing their production costs, and suitable to be used as stabilizers of perfluoropolyether oils and greases to prevent their degradation in the presence of metals, and the corrosion of the same metals, such as, e.g., Al, Ti, V, or their alloys, when operating in oxidizing and high-temperature environments.
