Swiss cheese or slices? A two‐step method has been developed for the preparation of the title membranes from lytropic liquid crystals templated with poly(methyl methacrylate). The membranes have ordered mesopores and tunable macropore channels. The mesostructure of the membranes can be tailored by adjusting the concentration of the surfactant solution (see picture: 1=low, 2=high concentration).
