Cover: The image shows that CO2 molecules diffuse through cavities formed by the presence of triptycene moieties in polymers. High fractional free volume elements due to 3-dimensional rigid framework lead to high gas selectivity as well as high permeability in polymeric membranes with highly tolerant CO2 plasticization, which can be a promising membrane material for CO2 capture applications. Further information can be found in the article by Y. J. Cho, H. B. Park* on page 579.
