The size- and structure-dependent optical properties of metal clusters have been studied for many years. In the
smallest size regime, every single atom is known to have a high impact on both the cluster geometry and optical properties [1].
Several years ago, first studies on the collective optical characteristics and interactions between multiple clusters, and the influence of their orientation were carried out [2]. Recently, it has been predicted that porphyrin templates may be used to produce well defined arrangements of small metal clusters [3]. However, so far, no experimental verification exists. We investigated the possibility to combine cationic Cu3 clusters with single porphyrins in a collision cell. This represents a first step towards investigating metal clusters on porphyrin templates in the gas phase.
