Unlocking Long‐Lived Charge‐Separated State in Pentamethine Cyanine Based on Anionic Hofmeister Effect for Photodynamic Immunotherapy

open access: yesAdvanced Science, EarlyView.
Based on the anionic Hofmeister effect, a universal strategy of incorporation of stereo‐π anion BPh4− into a series of Cy5 skeletons to unlock long‐lived charge‐separated states was reported, wherein the weak electronic coupling and low charge recombination driving force hinder the charge recombination process, elevating the oxygen‐independent ROS ...

Local Acidity as a Corrosiveness Descriptor of Fluorinated Ether Solvents in Lithium–Metal Batteries

open access: yesAngewandte Chemie, EarlyView.
Adjusting the extent of solvent fluorination reveals a trade‐off between the solvation power and solvent acidity of electrolytes for lithium–metal batteries (LMBs). F4MEP is within the optimal window and balances anion‐rich solvation with suppressed Li corrosion for stable interphase formation to extend the cycle life of LMBs.

Decoding dihedral angles in melt-bearing and solidified rocks

open access: yes, 2010
The dihedral angle is the angle subtended between two grain boundaries at a three-grain junction, or the angle between the two liquid-solid interfaces at the corner of a fluid-filled pore.

Noncanonical Peloruside A Biosynthesis by an Uncultivated Verrucomicrobiota Symbiont

open access: yesAngewandte Chemie, EarlyView.
Noncanonical biochemistry of the peloruside PKS characterized in this work, comprising double bond generation by a noncanonical tridomain (blue), acetyl‐CoA recycling (orange), and proofreading systems (purple and yellow). The Z‐double bond is installed by TEB1 through O‐acetylation and acetate elimination. The acyl ligase PelB (AL, orange) selectively

The Harborth Constant of Dihedral Groups

open access: yes, 2018
The Harborth constant of a finite group $G$, denoted $\gs(G)$, is the smallest integer $k$ such that the following holds: For $A\subseteq G$ with $|A|=k$, there exists $B\subseteq A$ with $|B|=\exp(G)$ such that the elements of $B$ can be rearranged into a sequence whose product equals $1_G$, the identity element of $G$. The Harborth constant is a well

Core and π‐Bridge Engineering to Deconstruct Y6‐Series into Modular Non‐Fused Acceptors: DFT‐Guided Structure‐Property Map for Organic Solar Cells

open access: yesAdvanced Electronic Materials, EarlyView.
The rigid fused backbone of Y6‐series acceptors is deconstructed into a modular, non‐fused A‐π‐A′‐π‐A architecture. Comprehensive quantum chemical simulations reveal that strategic core and π‐bridge engineering preserves strong near‐infrared light‐harvesting and enhances intramolecular charge‐transfer character.

Cysteine Thioaldehydes: Photolytic Generation, Reactivity, and Biological Implications

open access: yesAngewandte Chemie, EarlyView.
Photolysis of cysteine phenacylsulfides bearing non‐conjugating electron‐withdrawing substituents leads to high conversions into cysteine thioaldehydes through a Norrish type‐II pathway. This methodology enabled the study of the aqueous reactivity of these important biosynthetic intermediates, which, depending on peptide sequence, pH and buffer ...
