What is Capture of Sulfur Mustard by Pillar[5]arene: From Host-Guest Complexation to Efficient Adsorption Using Nonporous Adaptive Crystals about?

## Summary Sulfur mustard (SM) has been the most frequently used chemical warfare agent. Here, we present the efficient containment of SM and its simulants by __per__-ethylated pillar[5]arene (EtP5). EtP5 exhibited strong binding abilities toward SM and its simulants not only in solution but also in the solid state. The association constant (__K__~a~) between SM and EtP5 was determined as (6.2 ± 0.6) × 10^3^ M^−1^ in __o__-xylene-__d__~10~. Single crystal structure of SM@EtP5 showed that a 1:1 inclusion complex was formed, which was driven by multiple C–H···π/Cl/S and S···π interactions. In addition, activated crystal materials of EtP5 (EtP5__α__) could effectively adsorb SM simulants at solid-vapor phase; powder X-ray diffraction patterns and host-guest crystal structures indicated that the uptake process triggered a solid-state structural transformation. More interestingly, the captured guest molecules could be stably contained in EtP5__α__ for at least 6 months in air at room temperature.
