Nested non-covalent interactions expand the functions of supramolecular polymer networks.

Supramolecular polymer networks contain non-covalent cross-links that enable access to broadly tunable mechanical properties and stimuli-responsive behaviors; the incorporation of multiple unique non-covalent cross-links within such materials further expands their mechanical responses and functionality. To date, however, the design of such materials has been accomplished through discrete combinations of distinct interaction types in series, limiting materials design logic. Here we introduce the concept of leveraging "nested" supramolecular crosslinks, wherein two distinct types of non-covalent interactions exist in parallel, to control bulk material functions.

Noncovalent Grafting of Molecular Complexes to Solid Supports by Counterion Confinement.

Grafting molecular complexes on solid supports is a facile strategy to synthesize advanced materials. Here, we present a general and simple method for noncovalent grafting on charge-neutral surfaces. Our method is based on the generic principle of counterion confinement in surface micropores.

PdML (for = 6, 8, 12) nanospheres by post-assembly modification of PdL spheres.

In this contribution, we describe a post-assembly modification approach to selectively coordinate transition metals in PdL cuboctahedra. The herein reported approach involves the preparation of PdL nanospheres with protonated nitrogen donor ligands that are covalently linked at the interior. The so obtained Pd(LH) nanospheres are shown to be suitable for coordinative post-modification after deprotection by deprotonation.

Broadening the catalytic region from the cavity to windows by ML nanospheres in cyclizations.

Supramolecular cages have received tremendous attention as they can contain catalysts that exhibit confinement effects in the cavity, leading to excellent performances. Herein, we report an example wherein the catalytic region is extended from the cage cavity to the windows, and investigate its confinement effect by utilizing the PdL cage that contains rigidly fixed and isolated gold complexes at the windows. PdL exhibit three features of particular interest while assessing their properties in gold-catalyzed cyclization reactions.
