77_02/2012Cover Picture: Scaffold-Optimized Dendrimers for the Detection of the Triacetone Triperoxide Explosive Using Quartz Crystal Microbalances (ChemPlusChem 2/2012)

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.
