Abstract

Striped, bimetallic Au-Pt-Au rod-shaped colloidal particles were fabricated. The different chemical reactivities of Pt and Au towards thiols and isocyanides were found to influence spatially-selective chemical modification within individual nanoparticles. The preparation and chemical manipulation of anisotropic colloidal building blocks represent a first step towards anisotropic mesoscale assembly and other materials chemistry applications. It is possible to make segmented multi-metal rods of controllable length by electroplating in a porous template membrane. It is also possible to control the surface chemistry of different metals within a single colloidal particle, after it has been released from the membrane, by means of orthogonal self-assembly.
