Abstract: | A multilayer comprising nanogold particles and organic molecules was constructed by self-assembly of the small organic molecule 1-phenyl-5-mercaptotetrazole onto the octadecylamine-protected nanogold monolayer in the course of transferring the monolayer, layer by layer, from a Langmuir-Blodgett trough to solid substrates. The structure and properties of the constructed multilayer were characterized by TEM images and ATR-IR, XPS, and UV-vis spectra. It is evidenced for the first time that the combination of Langmuir-Blodgett and self-assembly techniques provides a new way to organize functional nanoparticles such as organic-nanogold complexes. |
