Beyond the Edge: Charge‐Transfer Excitons in Organic Donor‐Acceptor Cocrystals

Advanced Functional Materials, EarlyView.
Complex excitonic landscapes in acene–perfluoroacene cocrystals are unveiled by polarization‐resolved optical spectroscopy and many‐body theory. This systematic study of a prototypical model system for weakly interacting donor–acceptor compounds challenges common views of charge‐transfer excitons, providing a refined conceptual framework for ...

1D versus 2D cocrystals growth via microspacing in-air sublimation

Nature Communications, 2019
Organic cocrystals have interesting properties owing to synergistic effects of the individual components but development of effective growth methods for molecular cocrystals is still in its primary stage. Here the authors demonstrate a sublimation method

Peptide‐Induced Ferroelectricity in Charge‐Transfer Supramolecular Materials

Advanced Materials, EarlyView.
Bio‐inspired supramolecular charge‐transfer amphiphiles self‐assemble into nanoribbons in water, where peptide chirality‐induced symmetry breaking generates robust ferroelectricity across multiple systems. These water‐processable organic ferroelectrics also enhance neuronal outgrowth and electrophysiological maturity, offering a versatile strategy for ...

HSP70 Interactome‐Mediated Proteolysis Targeting Chimera (HSP70‐PROTAC) for Ferroptosis‐Driven Cancer Treatment

Advanced Science, EarlyView.
This study reports a novel targeted protein degradation strategy termed “HSP70‐PROTAC” that recruits Hsc70 complex to a target protein for inducing degradation. Among them, GDAz‐3 exhibits effective GPX4 degradation activity via UPS/CMA processes, triggering ferroptosis‐driven anticancer activity in vitro and in vivo.

Consistency and variability of cocrystals containing positional isomers: the self-assembly evolution mechanism of supramolecular synthons of cresol–piperazine

IUCrJ, 2019
The disposition of functional groups can induce variations in the nature and type of interactions and hence affect the molecular recognition and self-assembly mechanism in cocrystals. To better understand the formation of cocrystals on a molecular level,
