“…Supramolecular polymers refer to polymeric arrays in which monomeric units are connected by noncovalent interactions in a directional and reversible manner. − The noncovalent nature endows supramolecular polymers with attractive properties, − such as reversibility − and stimuli-responsiveness, − which are not easily realized in their covalent counterparts, rendering them as desirable candidates for the fabrication and processing of dynamic materials. Although the research on supramolecular polymers has achieved significant development in the past decades, there are plenty of rooms for further investigation on new approaches of controllable supramolecular polymerization.…”

In this letter, we report a new method of controllable supramolecular polymerization, taking advantage of host-enhanced photodimerization. The low-molecular-weight supramolecular oligomers were formed by noncovalent complexation between cucurbit[8]urils (CB[8]) and the bifunctional monomers (DBN) with Brooker's merocyanine moiety (MOED) on either end. Interestingly, when irradiated with UV light, the supramolecular oligomers could transform into supramolecular polymers with high molecular weight. The molecular weight of supramolecular polymers could be controlled by varying the irradiation time. It is highly anticipated that this work can enrich the methods on the modulation of supramolecular polymerization.

“…Because we identified the photochemical properties of G1 in a previous work, [14] we expected that the [2]pseudorotaxane of trans-G1·DNC could be converted into cis-G1·DNC upon the photoinduced isomerization of the azobenzene group. As shown in Figure 3, the proton signals of cis-G1 could be readily distinguished from its trans isomer within the NMR timescale after irradiation at 365 nm for 30 min.…”

The synthesis of advanced molecular machines represents one of the significant topics in supramolecular chemistry. In this work, a multicomponent molecular machine was successfully constructed by the inclusion complexation of azophenyl derivative bearing pyridinium terminals (G1) with α-cyclodextrin (α-CD) and tetrasulfonated 1,5-dinaphtho-32-crown-8 (DNC) in water, which was comprehensively characterized

“…[15][16][17] An important approach is to construct photoresponsive supramolecular assemblies by introducing azobenzene into the supramolecular system as a photoresponsive switch to regulate the self-assembled morphology. 18,19 In recent decades, a variety of stimuli-responsive supramolecular systems have been successfully prepared based on the host-guest interaction of macrocyclic hosts involving cyclodextrin, 20,21 cucuraburon, 22 crown ether, 23 calixarene 24 and pillar[n]arene, [25][26][27] which have been widely used in various smart supramolecular materials. Pillar [n]arene is a new generation of supramolecular macrocyclic host first reported by Ogoshi et al in 2008.…”

The derivatization of pillar[n]arenes is a prerequisite for endowing them with functions, as well as enriching the application of pillar[n]arene materials in advanced material science. Herein, we report the self‐assembly of amphiphilic rim‐differentiated pillar[5]arene (H1). One side of the pillar[5]arene is composed of hydrophilic poly(ethylene oxide) chains, benzene and azobenzene groups connected with ether bonds, and the other side is composed of ethoxy groups. In CHCl3 solvent, the amphiphile H1 self‐assembled into spherical micelles, while in H2O/THF mixed solvent H1 self‐assembled into nanorod‐like assemblies. Interestingly, addition of a guest molecule composed of tetraphenylethene and hexanenitrile groups (G1) to the CHCl3 solution of H1 produces large sheet aggregates via the strong π–π stacking of rod segments. The reversible transformation between the nanosheet assemblies of host–guest complexes and nanoparticles is achieved by addition of the guest molecule 1,4‐butylamine (G2) and pillar[5]arene with ethoxy groups as competitive molecules. Notably, worm‐like and nanorod micelles of H1 were constructed in H2O/THF solution triggered by light irradiation, which assemblies can be used as photosensitive erasable writing materials. © 2023 Society of Industrial Chemistry.
