Mesoscopic order and the dimentionality of long-range resonance energy transfer in supramolecular semiconductors [PDF]

, 2008
We present time-resolved photoluminescence measurements on two series of oligo-p-phenylenevinylene materials that self-assemble into supramolecular nanostructures with thermotropic reversibility in dodecane.

Non‐Enzymatic Destruction of the Extracellular Matrix for Activatable Orthotopic Tumor Treatment and Enhanced Drug Penetration

Advanced Functional Materials, EarlyView.
Supramolecular biomimetic nanoaggregates (HFCu NAs), constructed with fluorinated histidine and copper ions via metal coordination and aromatic packing, exhibit enhanced reactive oxygen species （ROS）generation at tumor sites, which results in stepwise collapse of the extracellular matrix (ECM), affording tumor microenvironment responsive “turn‐on” 19F ...

Recognition-mediated hydrogel swelling controlled by interaction with a negative thermoresponsive LCST polymer [PDF]

, 2016
Most polymeric thermoresponsive hydrogels contract upon heating beyond the lower critical solution temperature (LCST) of the polymers used. Herein, we report a supramolecular hydrogel system that shows the opposite temperature dependence.

Self-healing metallo-supramolecular hydrogel based on specific Ni2+ coordination interactions of poly(ethylene glycol) with bistriazole pyridine ligands in the main chain [PDF]

, 2020
In this study, a supramolecular hydrogel formed by incorporating the 2,6-bis(1,2,3-triazol-4-yl)-pyridine (btp) ligand in the backbone of a polymer prepared by copper(I)-catalyzed alkyne-azide cycloaddition (CuAAC) "click" polyaddition reaction of 2,6 ...

An Engineered Recombinant Spider Silk Protein Providing Disulfide‐Locked Control over Self‐Assembly and Fiber Formation

Advanced Functional Materials, EarlyView.
Using atomic structure and local stability information, recombinant aciniform spider silk proteins are rationally engineered to incorporate a chemically switchable disulfide bond to prevent fiber formation. When disulfide‐locked, these proteins cannot form continuous fibers, whereas the unlocked (reduced) state can.

Iron-based trinuclear metal-organic nanostructures on a surface with local charge accumulation [PDF]

, 2018
Coordination chemistry relies on harnessing active metal sites within organic matrices. Polynuclear complexes - consisting of organic ligands binding to clusters of several metal atoms are of particular interest, owing to their electronic/magnetic properties and potential for functional reactivity pathways. However, their synthesis remains challenging;

Efficient light-induced phase transitions in halogen-bonded liquid crystals [PDF]

, 2016
Here, we present a new family of light-responsive, fluorinated supramolecular liquid crystals (LCs) showing efficient and reversible light-induced LC-to-isotropic phase transitions.

Predicting 2D Crystal Packing in Thin Films of Small Molecule Organic Materials

Advanced Functional Materials, EarlyView.
A computational method is proposed for predicting the 2D molecular packing in crystalline thin films of flexible organic molecules. The approach employs a grid search for molecular arrangements, achieving accurate predictions of 2D packing motifs with strongly reduced computational costs.

The interaction between cucurbit[8]uril and baicalein and the effect on baicalein properties

Beilstein Journal of Organic Chemistry, 2020
The host–guest interactions between baicalein (BALE) and cucurbit[8]uril (Q[8]) and the corresponding properties of the inclusion complex were studied using 1H NMR, IR and UV–vis spectroscopy and DTA.

Halogen bonding enhances nonlinear optical response in poled supramolecular polymers [PDF]

, 2015
We demonstrate that halogen bonding strongly enhances the nonlinear optical response of poled supramolecular polymer systems. We compare three nonlinear optical chromophores with similar electronic structures but different bond-donating units, and show ...
