摘要

Thiacalixarenes bearign phenylaxo or ethnylic groups on the lower rims were prepared and fullycharacterized.The functional groups were chosen for their ability to increased the electron delocalisationover the molecule and to form metal complexes.The formation of complexes bestween phenylazothiacalixarenes and metal salts(Zn~2+,Ag~+...),and the synthesis of platinum acetylides from ethnylthiacalixarenes were investigated.Preliminary studies on optical limiting properties for both ligands and complexes is reported.Clamping levels of approx4 muJ at 532 nm,were observed for both tetra9pentylphenylethynyl)teansmission).A second functionlisation (upper rims) with metal alkoxide groups has also been investigated in order to prpare hybrid materials incorporating the optically active molecule.The same macrocycle core was thus bifunctionalised,and used for its optical properties on one side and as a precursor of an inorganic network for hybrid materials on the other.
