Helical Single Crystals of Porous Hydrogen‐Bonded Organic Frameworks as a Candidate for Morphologically Functional Organic Materials

Angewandte Chemie, EarlyView.
Helical‐shaped crystals of a hydrogen‐bonded organic framework (HOF) with permanent porosity have been developed. The helical HOF shows expansion and contraction, respectively, upon desorption and adsorption of solvents. Moreover, doping of additive molecules can modulate the photophysical properties and morphology of the helical HOF, showing the ...

Organocatalytic desymmetrization provides access to planar chiral [2.2]paracyclophanes

Nature Communications
Planar chiral [2.2]paracyclophanes consist of two functionalized benzene rings connected by two ethylene bridges. These organic compounds have a wide range of applications in asymmetric synthesis, as both ligands and catalysts, and in materials science ...

Targeting the PHB2–ACSL3 Lipid‐Remodeling Axis Overcomes Cisplatin Resistance by Restoring Ferroptosis in Gastric Cancer

Advanced Science, EarlyView.
ABSTRACT Platinum‐based chemotherapy resistance remains a major obstacle in gastric cancer (GC) treatment. Through integrated transcriptomic profiling of cisplatin‐resistant xenografts and pharmacogenomic interrogation of the NCI‐60 dataset, we identified Prohibitin‐2 (PHB2) as a previously unrecognized determinant of chemoresistance.

An X‑Shaped Chiral Non‑Fullerene n‐Type Semiconductor: Application in Perovskite Solar Cells and Chirality‑Induced Spin Selectivity

Angewandte Chemie, EarlyView.
A highly electron‑accepting derivative of cyclobisbiphenylenecarbonyl (CBBC‐TIC) is reported. CBBC‐TIC functions as an electron‐transport layer for perovskite solar cells, achieving a power conversion efficiency of 20.6%. Furthermore, the enantiomers of CBBC‐TIC exhibited spin‐selective electron transport with high enantiospecific magnetic conductance ...

Chiral Separation of Mandelic Acid Derivatives Using Various Permethylated Cyclodextrin Selectors Containing Stationary Phases in GC

Molecules
A good chiral separation usually results in a trial-and-error process; however, through systematic studies, certain principles can be established to correlate structure with chiral selectivity.
