Gold nanoparticles (AuNPs) composite with the gold surface linked directly with the mesogen through in-situ generated siloxane has been synthesised and is hereby presented.  Silane conjunction approach was carried out by capping AuNPs with 11-Marcapto-1-Undecanol (AuNPMUD) while the laterally terminal alkene of the mesogen (1) was converted to triethoxysilane end group (2) by hydrosilylation reaction. The hydrolysis and condensation of the ethoxy group of the mesogen (2) with the hydroxyl group of the capped AuNPs afforded the nanocomposite (3). The nanocomposite showed smectic arrangement under polarised optical microscope.

Keywords: Gold nanoparticles; hydrosilylation; mesogen; nematic; nanocomposites.
