Novel molecular square membranes have been fabricated and the size‐selective transport of various probe molecules through them demonstrated by the authors. Measurement of the permeabilities of various sized molecules through thin films of pyrazine and zinc‐dipyridyl porphyrin molecular squares (see Figure) on polyester membrane supports have been performed.
