Angewandte Chemie, EarlyView.We develop new bifacial chiral non‐fullerene acceptors (NFAs) for organic solar cells (OSCs). Through comparative investigations of four NFAs including meso, racemic, and chiral entries, we demonstrate the superiority of homochiral NFAs for the first time.

Molecules, 2018 Chiroptical spectra such as electronic circular dichroism (ECD) are said to be much more sensitive to conformation than their non-chiroptical counterparts, however, it is difficult to demonstrate such a common notion in a clear-cut way.

Representation and use of chemistry in the global electronic age. [PDF]
, 2004 We present an overview of the current state of public semantic chemistry and propose new approaches at a strategic and a detailed level. We show by example how a model for a Chemical Semantic Web can be constructed using machine-processed data and ...

Modular Synthesis of Pyritide‐Inspired Macrocycles Featuring Bipyridine Motifs
Angewandte Chemie, EarlyView.A pyritide‐inspired build/couple/pair strategy yields a diverse macrocycle library. This approach expands chemical space and enables the discovery of 6paW, a potent anti‐ferroptotic agent. Abstract Macrocycles represent a promising class of drug‐like scaffolds with unique structural features and the ability to engage challenging targets such as protein–

Angewandte Chemie, EarlyView.Pd‐catalyzed reaction of homoallylic amides with phenyliodine(III) diacetate (PIDA) under Pd(II) catalysis delivers 6‐acetoxylated 5,6‐dihydro‐4H‐1,3‐oxazines through the formation of one C─C and two C─O bonds. Abstract We report a Pd(II)‐catalyzed migratory triple functionalization of terminal alkenes.
