摘要

Phosphinines with pendant phenol or catechol functionalities and their gold(I) complexes were synthesised and characterised by spectroscopic data and in one case by a single-crystal X-ray diffraction study. Reactions of ligands or complexes with TiO_2 or chloropropyl modified hexagonal mesoporous silica were then studied with the aim to immobilise ligands or complexes on the carrier by covalent tethering. ~(31)P MAS NMR studies revealed that immobilisation on TiO_2 was accompanied by complete degradation of the phosphinine moiety. Base induced coupling with chloropropyl modified silica produced a material that contained a mixture of several surface-bound phosphorus compounds. ~(31)P MAS NMR studies revealed that approx. 40 % of the ligand had retained its integrity whereas the remaining fraction had been converted into further, not unambiguously identified structures.
