Unravelling the Atomic Structure of a Metal‐Covalent Organic Framework Assembled from Ruthenium Metalloligands

Advanced Materials, Volume 37, Issue 13, April 2, 2025.
Metal‐covalent organic frameworks (MCOFs) are novel porous materials that exhibit the advantages of covalent and metal‐organic frameworks. However, it is extremely difficult to resolve their atomic structure and better understand their structure‐properties relation. This work utilizes a synergistic combination of advanced microscopy, spectroscopic, and

Polarization effects in the channel of an organic field-effect transistor

, 2005
We present the results of our calculation of the effects of dynamical coupling of a charge-carrier to the electronic polarization and the field-induced lattice displacements at the gate-interface of an organic field-effect transistor (OFET). We find that

Stimuli‐Responsive Low‐Frequency Terahertz Absorption ON‐OFF Switchability in Spin‐Crossover Material

Advanced Materials, EarlyView.
A switchable Fe(II)–Hg(II) coordination polymer exhibits reversible ON‐OFF terahertz (THz) absorption through temperature‐ and light‐induced spin‐crossover. The material shows strong, tunable THz responses linked to phonon modes around Fe(II) centers, supported by spectroscopic measurements and calculations.

Increasing the Stability of Deep Blue Phosphor‐Sensitized OLEDs Using the Polariton‐Enhanced Purcell Effect

Advanced Materials, EarlyView.
The polariton‐enhanced Purcell (PEP) effect is demonstrated to enhance the stability of the deep blue phosphor‐sensitized fluorescent (PSF) OLEDs by 3.1 X compared to PSF diodes lacking this effect. In addition, PSF‐OLEDs exhibit reduced EQE roll‐off and deep blue color emission.

A High‐Capacity Semiconductor Organic Polymer for Stable Aqueous Ammonium‐Ion Storage

Advanced Materials, EarlyView.
The dual challenges of solubility and low conductivity in aqueous ammonium ions storage using the tetraamino‐p‐benzoquinone material are addressed through an amidation reaction and the conjugation effect. The delocalization of electrons facilitates rapid charge transport and collection.

Parameters influencing high-efficiency transfection of bacterial artificial chromosomes into cultured mammalian cells

BioTechniques, 2003
Although bacterial artificial chromosomes (BACs) provide a well-characterized resource for the analysis of large chromosomal domains, low transfection rates have proven a significant limitation for their use in cell culture models.

Proton-Coupled Electron Flow in Protein Redox Machines [PDF]

, 2010
Electron transfer (ET) reactions are fundamental steps in biological redox processes. Respiration is a case in point: at least 15 ET reactions are required to take reducing equivalents from NADH, deposit them in O_2, and generate the electrochemical ...
