University de Bordeaux, Institut des Sciences Moleculaires, Groupe Matdriaux, Talence Cedex, France 

Alkynylorganotins have been chosen as target precursors for both fundamental and practical reasons  

Precursor Mole number of precursor introduced (mmol g ) Reaction time (h) Loading (mmol g M Chain density (chain nm ) 

The presence of the fluorous chain at the silica surface was unambiguously demonstrated by TGA-MS, XPS, and MAS NMR measurements, and the release of three hexyne molecules per chemisorbed chain
