In a subtle change in anchoring strategy, the preformed ferrocenyl/Pd complex, incorporating a propyltrimethoxysilane substituent, was reacted with the inner... 

APMS (2.139 g, 0.0356 mol Si02) which had been dried in a vacuum oven overnight at 110 °C were suspended in toluene and [3-(2-aminoethyl)-amino]propyltrimethoxysilane (0.672 g, 0.00297 mol) was added The mixture was then heated at reflux for 24 hours, cooled and filtered to recover the diamino-APMS... 

Extent of silane condensation (degree of polymerization). In order to provide insight into the extent of condensation of silanols and their phase separation as a function of time, the hydrolysis of propyltrimethoxysilane was... 

Silanes, y-aminopropyltriethoxysilane and methyltrimethoxysilane were obtained from Union Carbide (A1100 and A163 silanes, respectively), y-chloro-propyltrimethoxysilane was obtained from Petrarch Systems, Inc. 

Introduction of the Glutaraldehyde Spacer. The y-amino-propyltrimethoxysilane modified surface was treated with 5% v/v aqueous glutaraldehyde solution. The reaction was performed at ambient temperature for 24 hours. The film was washed with water and dried.
