Selective Charge Extraction Allows Fast Photomultiplication and Imaging in Rigid and Ultra‐Flexible SWIR Organic Photodiodes

Advanced Energy Materials, EarlyView.
SWIR donor polymer TQ‐3T allows photomultiplication in OPD in 1:1 ratio with NFA Y6, achieving EQEs > 1100% at ‐10 V. Microseconds response times are retained, amongst the lowest for photomultiplication. As proof of concept, we demonstrate ultrathin and flexible PM‐OPDs based on our TQ‐3T:Y6 as a flexible pulse oximeter as well as a conformable image ...

Rational Design of Donor‐Acceptor Oligomers for Enhanced Charge Separation

Advanced Physics Research, EarlyView.
How can molecular symmetry be broken to maximize photoinduced charge separation? Through first‐principles analysis of 22 DTP‐based donor‐acceptor ternary oligomers, this work establishes that combining architectural asymmetry with site‐selective acceptor fluorination creates an ideal electrostatic landscape for frontier orbital segregation.

Solvent Induced Disulfide Bond Formation in 2,5-dimercapto-1,3,4-thiadiazole [PDF]

, 2007
Disulfide bond formation is the decisive event in the protein folding to determine the conformation and stability of protein. To achieve this disulfide bond formation in vitro, we took 2,5-dimercapto-1,3,4-thiadiazole (DMcT) as a model compound. We found

Design Principles for Next Generation of Small Organic Molecules for Photodynamics Therapy Revealed by Nonadiabatic Molecular Dynamics

Chemistry – A European Journal, EarlyView.
Molecular design reshapes the landscape of excited‐state relaxation. Nonadiabatic dynamics reveal how electronic structure guides population flow between competing pathways beyond static energetic arguments. ABSTRACT Nitrobenzochalcogenadiazole derivatives are emerging candidates for photodynamic therapy (PDT), yet the precise mechanisms governing ...
