TL;DR: A series of triple chain azobenzene based rod-like compounds is investigated that show mirror-symmetry breaking in an isotropic liquid occurring adjacent to a lamellar LC phase, affected by trans-cis photoisomerization.

TL;DR: The chiral phases, resulting from spontaneous mirror symmetry breaking, represent conglomerates of macroscopic chiral domains eventually leading to uniform chirality.

TL;DR: In this article, the first examples of light-responsive halogen-bonded supramolecular polycatenars were designed and prepared via halogen bond formation between a non-mesogenic taper shaped tetrafluoroiodobenzene based halogen donor and nonmesogenic or mesogenic azopyridine derivatives as halogen acceptors.

TL;DR: A quantitative model relating molecular architecture to the space-filling requirements of six possible bicontinuous cubic phases is presented, that is, the single- and double-network versions of gyroid, diamond, and "plumber's nightmare".

TL;DR: There is a remarkably strong effect of the position of fluorination; polar order is favored by peripheral core substitution and is suppressed by inside-directed fluorination in inorganic solid-state ferroelectrics.
