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

Journal 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.

Targeting the DNA-binding activity of the human ERG transcription factor using new heterocyclic dithiophene diamidines [PDF]

, 2012
Direct modulation of gene expression by targeting oncogenic transcription factors is a new area of research for cancer treatment. ERG, an ETS-family transcription factor, is commonly over-expressed or translocated in leukaemia and prostate carcinoma. In

Resonant X‐Ray Diffraction of Conjugated Polymers at the Selenium K‐Edge

Macromolecular Rapid Communications, EarlyView.
Analogous to isomorphous replacement used in X‐ray crystallography studies of proteins, substituting sulfur for selenium in conjugated polymers enables resonant diffraction studies of molecular packing down to the length scale of π‐‐π stacking. Two selenium‐containing polymers are studied with a comparison made between sulfur K‐edge and selenium K‐edge

Transition-metal norharmane compounds as possible cytotoxic agents: new insights based on a coordination chemistry perspective [PDF]

, 2016
New first-row transition-metal compounds with the ligand norharmane (9H-Pyrido[3,4-b]indole; Hnor) are reported. The compounds have the general formula [M(LL)(Hnor)(NO3)2](MeOH)0–1 (M = Co, Ni, Cu, Zn; LL = 2,2′-bipyridyl (bpy), 1,10-phenanthroline (phen)

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

Polymer 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.

Die Elektronenanregungsspektren der Phenanthroline

Zeitschrift 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.

Conjugated Polymers Engineered for Flexible/Stretchable Electronics

Journal 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.

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

Pest 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

Small, 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.

Nickel Foam Electrodes—A Versatile, Powerful, and Readily Available Tool in Electro‐Organic Synthesis

The Chemical Record, EarlyView.
Nickel foam—one material, two faces, and several versatile roles depending on electrolytic conditions. For more than 50 years, nickel foam electrodes have served in electrosynthesis as powerful and readily available electrode materials. Due to their inexpensive nature and easy handling, they have been widely employed.
