Synthesis and Characterization of Juglone‐Derived cu (II), Mn (II) and Zn (II) Complexes and Investigation of Their Cytotoxic Activities Against Lung and Colon Cancer Cells in Vitro and in Silico

open access: yesJournal of Applied Toxicology, EarlyView.
ABSTRACT Three new Zn (II), Cu (II) and Mn (II) complexes have been synthesized from 5‐hydroxy‐1,4‐naphthoquinone (HNQ). Elemental analysis, magnetic susceptibility, UV–Vis, IR and Mass spectrometry have all been used to explore the structural characterization of these compounds.

Preparation of 4,7‐Dihalobenzo[b]Thiophene Derivatives Containing Iodine Atoms and Their Cross Coupling With Arylethynes

open access: yesJournal of Heterocyclic Chemistry, EarlyView.
Quasi T‐shaped three‐way benzo[b]thiophene scaffolds, containing iodine atom(s) at the 4‐ and/or 7‐position, were prepared by several methods such as silica gel‐assisted cyclization. The iodobenzo[b]thiophenes thus prepared were subjected to Sonogashira cross couplings to give various ethynylbenzo[b]thiophenes.

An all‐polymer blend for photovoltaic applications: A combined photoabsorption, photoemission and ab initio multi‐configurational study

open access: yesPolymer International, EarlyView.
Near‐edge X‐ray absorption fine structure, X‐ray photoelectron spectroscopy and multi‐configuration self‐consistent field results show, respectively, preferential edge‐on and face‐on orientations for the thiophene and naphthalene diimide units of the PBDB‐T‐SF:P(NDI2OD‐T2) all‐polymer blend, and surface accumulation of the acceptor.

Conjugated Polymers Engineered for Flexible/Stretchable Electronics

open access: yesJournal of Polymer Science, EarlyView.
This review highlights glass transition temperature (Tg) as the central parameter linking molecular structure to device performance in conjugated polymers. By tuning backbone rigidity, side‐chain architecture, and dynamic bonding, Tg governs the balance between π–π stacking–enabled charge transport and mechanical compliance.

Crystal structure of 11-[4-(hexyloxy)phenyl]-1,2,4-triazolo[4,3-a][1,10]phenanthroline

open access: yesActa Crystallographica Section E: Crystallographic Communications, 2015
The title compound, C25H24N4O, was prepared from 2-chlorophenanthroline and hexyloxyphenyltetrazole. The main difference between the two independent molecules (A and B) in the asymmetric unit is the orientation of the all-anti-configured hexyloxy chain ...

Translocation arrest by reversible folding of a precursor protein imported into mitochondria [PDF]

open access: yes, 1989
Passage of precursor proteins through translocation contact sites of mitochondria was investigated by studying the import of a fusion protein consisting of the NH2-terminal 167 amino acids of yeast cytochrome b2 precursor and the complete mouse ...

Die Elektronenanregungsspektren der Phenanthroline

open access: yesZeitschrift für Naturforschung A, 1967
Zur Deutung der Elektronenanregungsspektren der 10 isomeren Phenanthroline wurden SCF-CI-Berechnungen mit 30 Konfigurationen durchgeführt. Es zeigt sich, daß Lage, Intensität und Polarisation der Elektronenübergänge mit Hilfe dieser Methode sehr gut wiedergegeben werden.

Fendioxypyracil, a new and systemic PPO‐inhibiting herbicide for X‐spectrum weed control

open access: yesPest Management Science, EarlyView.
This graphical abstract presents the discovery and synthesis of PPO herbicide structures with a central pyridine core, showing molecular conformations, dose–response inhibition curves for PPO1 and PPO2, and comparative weed and grass control efficacy of fendioxypyracil versus other herbicides in greenhouse and field trials.

External Stimuli‐Activable Single‐Atom Nanozymes for Bioapplications

open access: yesSmall, EarlyView.
Stimuli‐activable single‐atom nanozymes (SANs) are reviewed from materials design to biomedical applications. We explain electronic‐structure tuning principles and synthesis strategies that maximize the responsiveness of metal active sites and supports to light, ultrasound, and magnetic fields.
