In this paper, the synthesis of gold(I)-calix[8]arene complexes from benzyloxycalix[8]arene used as a starting material is reported. 8 or 16 trimethylphosphine-gold(I) are grafted to the calix[8] arene via a C4 alkane chain linker and a thiolate group. The formed gold(I)-complexes are well-characterised by NMR spectroscopy. We also show that these complexes can act as both source of metal and stabilizing agent for the formation a gold nanoparticles as the radiolytic reduction of these complexes produces small monodisperse nanoparticles.
