Steering the Self‐Assembly Outcome of a Single NDI Monomer into Three Morphologically Distinct Supramolecular Assemblies, with Concomitant Change in Supramolecular Polymerization Mechanism

Advanced Science, 2019
Noncovalent self‐assembly creates an effective route to highly sophisticated supramolecular polymers with tunable properties. However, the outcome of this assembly process is highly dependent on external conditions.

Temperature‐Enhanced Supramolecular Polymer Adhesion Provided by Concurrent Utilization of Calix[4]Pyrrole and Crown Ether Molecular Recognition

Advanced Functional Materials, EarlyView.
Simultaneous utilization of calix[4]pyrrole‐ and crown ether‐based molecular recognition allows the construction of a high molecular weight alternating supramolecular polymer. This heat processible polymer can be used as a durable and reusable adhesive on glass and steel with temperature‐enhanced adhesion strength without the need for a solvent ...

Supramolecular Zwitterionic Hydrogels for Information Encryption, Soft Electronics and Energy Storage at Icy Temperature

Advanced Functional Materials, EarlyView.
A series of ACHPES‐based hydrogels are developed and realizing multiple functions like anti‐fouling properties, alkali‐induced color/fluorescence‐changing ability and strain sensing. Furthermore, the hydrogels show excellent anti‐freezing performance, whose optical, mechanical and electrical properties remain stable at −47.3 °C.

Thermoreversible Associating Polymer Networks: I. Interplay of Thermodynamics, Chemical Kinetics, and Polymer Physics [PDF]

, 2009
Hybrid molecular dynamics/Monte Carlo simulations used to study melts of unentangled, thermoreversibly associating supramolecular polymers. In this first of a series of papers, we describe and validate a model that is effective in separating the effects of thermodynamics and chemical kinetics on the dynamics and mechanics of these systems, and is ...

Antioxidant and Anti‐Senescence Polyvinyl Alcohol‐Gallic Acid Supramolecular Hydrogels for Stem Cell Culture

Advanced Healthcare Materials, EarlyView.
The PVA‐GA hydrogel is formed through hydrogen bonding between PVA hydroxyl groups and GA galloyl units, enabling sustainable GA release and its extended biological activity. The hydrogel scavenges ROS to reduce oxidative stress, preventing mitochondrial damage from excessive ROS, mitigating hADSC senescence, and preserving VEGF secretion, offering a ...

Supramolecular Additive Screening to Engineer Microfibrous Rafts for Expansion of Pluripotent Stem Cells in Dynamic Suspension

Advanced Healthcare Materials, EarlyView.
Segmented PCL‐bisurea (BU) polymers and BU‐peptide conjugate additives assemble into fibrous superstructures at the nanoscale through a mix‐and‐matching strategy. Different bioactivities are incorporated through variation of peptide sequences. The resulting materials are screened for their effect on stem cell adhesion and pluripotency.

Mesoporous phenolic/carbon materials templated by CO2-based PEO-b-PCHC diblock copolymers through mediated competitive intermolecular hydrogen bonding interactions for CO2 capture

Journal of CO2 Utilization
The CO2-based diblock copolymer, poly(ethylene oxide-b-cyclohexene carbonate) (PEO-b-PCHC), was synthesized via ring opening copolymerization (ROCOP) by using PEO as a macro-chain-transfer agent. Theses diblock copolymers were comprehensive characterized
