Abstract

This project was conducted in the laboratory of Professor Christopher B. Murray at the University of Pennsylvania. The project described herein includes the synthesis of a Janus dendrimer as well as complimentary dendrimers of hydrophobic and hydrophilic nature to study the self-assembly and organizational properties of these molecules on gold surfaces. A complete synthesis and characterization of these molecules is described, as well as grafting the molecules onto both gold nanoparticle and thin film surfaces. How the different dendritic molecules guide self-assembly of the nanoparticles and how the Janus molecule assembles itself on a gold surface was studied. To characterize these systems, TEM and solid state UV-vis were employed, and general trends are described herein.
