On page 605, Takuji Hirose and colleagues describe their work concerning triphenylene‐derived liquid crystals bearing six cinnamate moieties with two long alkoxy (C 10 ‐C 14 ) terminal chains at the meta ‐ and para ‐positions. They can spontaneously form not only fibers in liquid paraffin, but also porous flat membranes from various organic solvents such as benzene (as seen in the cover images), toluene, THF, and chloroform. The morphology and columnar structure of the membranes can be fixed by photo‐crosslinking between the cinnamate units, while the progress of the reaction takes some time. (DOI: 10.1002/pola.29299 )
