Crystals with broad robust channels are rare, especially if self‐assembled without the aid of metal ions. Three such crystals were prepared based on a common steroid motif. The channels formed are chiral, directional, aligned, and wide enough (>1 nm) to accept a variety of guests (see picture; red: oxygen, blue: nitrogen, green: fluorine).
