A new anion binding motif based on triptycene core has been synthesized from 2,7,14-trinitrotriptycene. Its well-defined binding pocket allowed for the selective recognition and sensing of dihydrogenphosphate in DMSO-d6 + 0.5% H2O.

Triptycene was used to build a series of ligands containing pyrazine groups for use in forming coordination frameworks and as model compounds toward target shape-persistent dendrimers and macrocycles. The phenylenediamine precursors are formed by controlled double nitration/reduction of triptycene, followed by condensation with triptycenyl o-quinone to form the ligands. Solid-state structures show

Switchable host system: Azobenzenes have been attached to a triptycene scaffold in the meta position. Isomerization experiments revealed efficient switching of azobenzene moieties together with the build-up of a cavity in the all-Z conformation of the C3v-symmetric trisazobenzene-triptycene; this makes this molecule interesting as a switchable host system. Moreover, computational studies indicated

majority of shape-persistent self-assembled organic cages are accessed via precipitation and studied in the solid state. Herein, we show that metastable iminecages (unsuitable for precipitation) can be trapped directly by in situ Pinnick oxidation conditions, yielding soluble, robust amide cages. Unlike the by-passed iminecages, the resulting cages are tolerant of hydrolysis conditions to unmask internal
