Tough Injectable Hydrogels Enabled by Integrating Rigid Homogeneous Framework With Flexible Chains

open access: yesAdvanced Functional Materials, EarlyView.
Tough injectable hydrogels are constructed by integrating a rigid, homogeneous hyaluronic acid framework with flexible long‐chain connectors. This framework–flexible structure simultaneously enhances network uniformity and promotes effective energy dissipation by enlarging plastic deformation zones under compression.

Shape‐Controlled Guanine Self‐Assemblies for Stable and Fast‐Ion Solid–Electrolyte Interphases in Sustainable Li Metal Batteries

open access: yesAdvanced Functional Materials, EarlyView.
The shape of guanine self‐assemblies is tuned by introducing alkyl (G8), fluoroalkyl (G8f), and oligoether (G8g) side chains into the G moiety. The scanning tunneling microscopy results and calculations show that the presence and type of the side chain strongly affect the G self‐assembly network.

The Role of Ultra‐Thin Buffer Layers for Achieving Ultra‐Low Dark Currents in Single‐Component Organic Photodetectors

open access: yesAdvanced Functional Materials, EarlyView.
Here, SubNc single‐component organic photodiodes (SC‐OPDs) are investigated, which achieve highly competitive performance metrics, including high EQE, ultra‐low JD, and high specific detectivity (D*). This study emphasizes the critical role of an organic buffer layer in studying the interface energetics and effects to achieve state‐of‐the‐art ...

Substituent Effects in Ugi–Smiles Reactions

open access: yesThe Journal of Physical Chemistry A, 2013
In a recent communication, we described the mechanism of the well-known Ugi-type reactions with a model system (J. Org. Chem. 2012, 77, 1361-1366). Herein, focusing on the Ugi-Smiles coupling, we study the effects of each of the four reactants on the energy profile to further explain the experimental results.

Substituent Effects in Chain‐Breaking Aryltellurophenol Antioxidants [PDF]

open access: yesChemistry – A European Journal, 2018
Abstract2‐Aryltellurophenols substituted in the aryltelluro or phenolic parts of the molecule were prepared by lithiation of the corresponding tetrahydropyran‐protected 2‐bromophenol, followed by reaction with a suitable diaryl ditelluride then deprotection. In a two‐phase system containing N‐acetylcysteine as a co‐antioxidant in the aqueous phase, all

Investigation of Halogen Substitution Effects in π‐Conjugated Organic Ligands of Chiral Hybrid Perovskites on Their Chiroptical Activity

open access: yesAdvanced Functional Materials, EarlyView.
The role of novel thiophene‐based ligands with halogen substitutions in enhancing the chiroptical and optoelectronic properties of 2D chiral HOIPs has been investigated. By tailoring ligand design, enhanced CD and CPL properties are achieved, with improved CPL discrimination in photodetectors.
