General description

Triptycene is the structural building block for triptycene-based polymer of intrinsic microporosity due to its rigid, fused-ring skeleton and three-fold symmetry. Triptycene-based cylindrical macrotricyclic polyether containing two dibenzo[24]crown-8 cavities has been synthesized and proved to be a highly efficient host for the complexation with paraquat derivatives.

Application

Triptycene was used in determination of diffusion coefficients of radical ions of hexafluorobenzene, diphenylacetylene, triptycene and tetraphenylnapthalene in liquid n-hexane and n-hexadecane.
