Description
Summary:	The preparation of micrometer to nanometer‐sized building blocks that can be selectively derivatized is reported here. Segmented multi‐metal rods of controllable length (see Cover) were fabricated by electroplating in porous template membranes. Additionally it is shown how the surface chemistry of different parts within a single particle can be controlled by means of orthogonal self‐assembly. Exploiting of the different reactivities of Pt and Au towards thiols and isocyanides leads to the observation of fluorescence from only the Au segments of the rods.
