Substituent effects on non-covalent interactions

, 2020
Non-covalent interactions play a vital role in biological and chemical systems, underpinning important processes such as ligand–receptor binding and protein structure. Substituent effects on these non-covalent interactions are often used to influence the system and are generally predicted based upon empirically defined constants.

Microporous Microgel Assemblies Facilitating the Recruitment and Osteogenic Differentiation of Progenitor Cells for Bone Regeneration

Advanced Functional Materials, EarlyView.
There is a significant need for biomaterials with well‐defined stability and bioactivity to support tissue regeneration. In this study, we developed a tunable microgel platform that enables the decoupling of stiffness from porosity, thereby promoting bone regeneration.

Non-covalent interactions in lubricant chemistry

, 2015
Lubricant formulations are highly complex mixtures, containing a multitude of additives, each geared towards improving the efficiency of often highly specialised processes. The study of lubrication, or tribology, is a huge area of research, but is often overlooked by chemists in favour of pharmaceutical or agrochemical research.

Backbone Heterojunction Photocatalysts for Efficient Sacrificial Hydrogen Production

Advanced Functional Materials, EarlyView.
Herein, a ‘single‐component’ organic semiconductor photocatalyst is presented in which a molecular donor is bonded to a polymer acceptor. The resultant material demonstrates exceptional photocatalytic activity for hydrogen evolution in aqueous triethylamine with an outstanding external quantum efficiency of 38% at 420 nm.

Self‐Immolative Activatable Nanoassembly toward Immuno‐Photodynamic Therapy in TME

Advanced Functional Materials, EarlyView.
A quinone methide‐gated, self‐immolative, H2O2‐responsive nano‐photosensitizer (Pyz/PS) is developed for targeted immuno‐photodynamic therapy. Pyz/PS selectively activates within tumor microenvironments, restores photosensitizer activity, generates ROS, and depletes intracellular GSH, enhancing oxidative stress.

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

Nature Communications
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 ...

Dendrimer assembly via non-covalent interactions

, 2020
Dendrimerler bir çekirdek etrafinda yapılanan, yüksek derecede dallanmış, tek dağılımlı moleküllerdir. Dendrimeri oluşturan parçalar dendron olarak adlandırılırlar. Genel kanı olarak dendrimerlerin, bütün dendronların tek bir çekirdek etrafında büyüyerek sentezlendiği düşünülür.
