The cover picture shows a quartz microbalance which is capable of tracing vapors of the explosive triacetone triperoxide (TATP) on a ppb level. The quartz crystal in such 200 MHz piezoelectric devices is about 5 mm in diameter and is coated with high‐performance dendrimers, which are schematically indicated by a tree. In their Communication on page 102 ff., S. R. Waldvogel and K. Müllen et al. report on scaffold‐optimized phenylene dendrimers that provide outstanding selectivity and affinity for tracing the explosive material. The peroxide molecules are accommodated in the voids defined by the branches of the dendritic architecture.
