Ferrocene‐Based Self‐Assembled Monolayers Enable Ultra‐High Specific Detectivity in Perovskite Photodetectors

Advanced Materials, EarlyView.
We report perovskite photodetectors with record specific detectivities exceeding 1013 Jones with a novel molecular design strategy to functionalize self‐assembled monolayers (SAMs) with ferrocene (Fc) derivatives. Fc‐SAM‐based devices also exhibit strong operational stability and enable data transmission rates exceeding 1 Mbps in a LiFi system ...

Adaptive Supramolecular Interactions Govern Redox‐Active Molecules in Aqueous Redox Flow Batteries

Advanced Materials, EarlyView.
Adaptive supramolecular interactions overcome the solubility‐stability trade‐off in aqueous redox flow batteries. Hydrophobic anions disrupt intrinsic π–π stacking to enable high solubility, while redox‐state‐dependent spin pairing and cation coordination dynamically stabilize reactive intermediates during operation.

Studies on Transition Metal-Quercetin Complexes Using Electrospray Ionization Tandem Mass Spectrometry

Molecules, 2015
To systematically study the effects of the number of d electrons of the first transition metal ions (Fe, Co, Ni, Cu and Zn) on the formation and stability of metal flavonoid complexes, we took the quercetin/M2+ complex as a model system to investigate ...

Molecular Appendix Adjusted Architectural Propagations of Red‐Light Controlled Macroscopic Photoactuating Performances

Advanced Robotics Research, EarlyView.
Amphiphilic chloroazobenzenes, bearing different amino acids as end groups alanine, phenylalanine, and valine, exhibit excellent photoisomerizations. Varying structures of three amino acid groups participate in supramolecular formations and therefore photoinduced morphological transformations via adjusting intermolecular interactions. These interaction
