On the rung way : Concerted self‐organization of an α,ω‐bis(triphenylenetetrahydroxy)disiloxane through π–π‐stacking and H‐bonding interactions generates a supramolecular channel in which silanol groups are entrapped between two hydrophobic columns. Ordered polycondensation leads to a high‐molecular‐weight, soluble, ladder cis ‐isotactic polysilsesquioxane (see picture).
