We designed basket 1 to comprise a C3-symmetric hydrophobic cage (477 Å(3)) at its southern edge and three polar ammonium caps at the northern edge. This amphiphilic molecule was observed to assemble into large unilamellar vesicles (350 nm, TEM) in water and thereby entrap dimethyl phenylphosphonate (184 Å(3)) in its cavity (K(app) = (1.97 ± 0.02) × 10(3) M(-1)). The entrapment of the organophosphonate, akin to soman in size (186 Å(3)), triggers the transformation of the vesicular material into nanoparticles (100 nm, TEM). Stimuli-responsive vesicles, containing baskets of type 1 in their bilayer membrane, are unique assemblies and important for obtaining novel sensing devices.

Due to the fascinating structures and wide applications, porous materials with open frameworks have attracted more and more attentions. Herein, a novel two‐dimensional (2D) halogen‐bonded organic framework (XOF–TPPE) was successfully designed and fabricated by iodonium‐bridged N⋅⋅⋅I+⋅⋅⋅N interactions between pyridyl groups and I+ for the first time. The formation of XOF–TPPE and its linear analogue was monitored by 1H NMR, UV–Vis, X‐ray photoelectron spectroscopy (XPS), IR, SEM, TEM, HRTEM and selected‐area electron diffraction (SAED). The structural model of XOF–TPPE was established based on powder X‐ray diffraction (PXRD) data and theoretical simulations. Significantly, synchrotron small‐angle X‐ray scattering (SAXS), DLS and UV–Vis spectroscopy experiments suggested that XOF–TPPE still maintains a stable 2D framework structure in solutions. This research opens up a novel avenue for the development of organic frameworks materials, and may bring new promising applications for the field of porous materials.

Into the fold: Intramolecular CH⋅⋅⋅O hydrogen bonding has been utilized to create new aromatic triazole foldamers. Remarkably, all the triazole units of the foldamers are guided to orientate inward to form a nitrogen ring. As a result, they can efficiently bind neutral tri‐ and didentate organohalogens through multiple N⋅⋅⋅X (X=Cl, Br, I) halogen bonds to form stable 1:1 complexes.

A novel type of chiral layered supramolecular copolymer with high molecular weight has been assembled from a hydrogen bonded C(6)-symmetric zinc porphyrin hexamer and chiral C(3)-symmetric pyridine hexadentate linkers driven by multivalent zinc porphyrin-pyridine coordination. UV-vis, circular dichroism, and static light scattering experiments revealed that the formation of the layered supramolecular copolymers is at first dynamically controlled and then becomes thermodynamically controlled.
