We find that while passive interfaces are one-dimensional the active ones exhibit two dynamical regimes: a passive-like regime and a propagating regime where the interfaces propagate until the entire domain is active nematic.

Herein, we systematically discussed the 2D crystallization of two categories of POSS-based SCGMs with constant building blocks ratio. Solution self-assembly of such SCGMs resulted in well-defined 2D nanosheets with similar structural configurations, showing great tolerance in the number of building blocks. Subsequently, we proposed a “sandwiched-type” mode to illustrate the bilayer 2D supramolecular framework, in which crystalline blocks pack in head-to-head manner. In addition, sequence isomers provide an ideal platform to further verify that the thickness of 2D nanocrystal is linked with the tethering density determined by the number ratio of building blocks.

The chirality of the Toc block enhanced the effective segregation strength of the BCO, leading to elevated order-order transition temperatures associated with the HPL-to-DG and DG-to-hexagonally packed cylinder (HEX) transitions. Within the HPL phase window, the chiral BCO exhibited significantly slower kinetics during thermally-induced structural reorganization in adjusting the <em>c/a</em> ratio, especially in the cooling process.
