Pillar[n]arene-Mimicking/Assisted/Participated Carbon Nanotube Materials. [PDF]

Materials (Basel), 2022
The recent progress in pillar[n]arene-assisted/participated carbon nanotube hybrid materials were initially summarized and discussed. The molecular structure of pillar[n]arene could serve different roles in the fabrication of attractive carbon nanotube-based materials.

Applications of Supramolecular Polymers Generated from Pillar[n]arene-Based Molecules. [PDF]

Polymers (Basel), 2023
Supramolecular chemistry enables the manipulation of functional components on a molecular scale, facilitating a “bottom-up” approach to govern the sizes and structures of supramolecular materials. Using dynamic non-covalent interactions, supramolecular polymers can create materials with reversible and degradable characteristics and the abilities to ...

A Biocompatible Liquid Pillar[n]arene-Based Drug Reservoir for Topical Drug Delivery. [PDF]

Pharmaceutics, 2022
Advanced external preparations that possess a sustained-release effect and integrate few irritant elements are urgently needed to satisfy the special requirements of topical administration in the clinic. Here, a series of liquid pillar[n]arene-bearing varying-length oligoethylene oxide chains (OEPns) were designed and synthesized. Following rheological

Calix[n]arene/Pillar[n]arene-Functionalized Graphene Nanocomposites and Their Applications. [PDF]

Front Chem, 2020
Calix[n]arenes and pillar[n]arenes, which contain repeating units of phenol and methane, are class of synthetic cyclic supramolecules. Their rigid structure, tunable cavity size, flexible functionalization, and rich host-guest properties make them ideal surface modifiers to construct functional hybrid materials. Introduction of the calix[n]arene/pillar[

Designing Tailored Molecular Cavities Using Calix[5]arenes as Building Blocks. [PDF]

Chem Rec
This account focuses on the shape and dimensions of cavities formed by precisely designed molecular frameworks. It highlights our efforts to construct synthetically tailored cavities based on calix[5]arenes. This study examines the shapes and dimensions of cavities defined by well‐designed molecular structures.

On the Stability and Formation of Pillar[n]arenes: a DFT Study [PDF]

The Journal of Organic Chemistry, 2021
The increased use of both pillar[5]arenes and pillar[6]arenes, stimulated by increasingly efficient syntheses of both, has brought forward the question as to what drives the intermediates in this Friedel-Crafts ring formation to form a pillar[5]arene, a pillar[6]arene, or any other sized macrocycle.

Selective Nitrate Transmembrane Transport Through Adaptive Weak C─H Bonding Cyanostilbene Water Channels

Angewandte Chemie, EarlyView.
Here we demonstrate that weak HB CH donor cyanostilbenes promote water/ion transport through their ability to form less‐ordered transient water channels within the lipid bilayer with increased water permeability and NO3−/ Cl− selectivity. ABSTRACT Transmembrane water transport strongly depends on how dynamic, translocating water clusters are stabilized

Cyclo‐Polyproline: Chameleonic All‐Peptide Macrocycles With Induced‐Fit Host‐Guest Recognition

Angewandte Chemie, EarlyView.
Macrocycles served as the genesis of supramolecular chemistry, advancing synthetic, separation, and materials fields. Despite their utility, they typically lack synthetic control. This work establishes a robust platform for all‐peptide macrocycles capable of host‐guest complexation and chameleonic behavior.

Molecular-Scale Porous Materials Based on Pillar[n]arenes [PDF]

Chem, 2018
Summary We begin this review with an introduction to pillar[n]arenes by showing the research history of macrocyclic compounds and the shape, chemical structure, host-guest properties, synthesis, and functionalization of pillar[n]arenes. We then present the modification of pillar[n]arenes on surfaces such as solid and porous surfaces for the creation ...

Dynamic Regulation of Supramolecular Chirality in an Amphiphilic Dimeric Macrocycle Through Azobenzene‐Based Photoisomerization

Advanced Science, EarlyView.
A stimuli‐responsive supramolecular system has been rationally designed enabling hierarchical control over supramolecular handedness. This hybrid architecture retains orthogonal host‐guest properties and displays unique amphiphilicity‐directed chiral self‐assembly.
