One-dimensional polymer chains consisting of π-conjugated porphyrin units are formed via Glaser coupling on a Ag(111) surface. Scanning probe microscopy reveals the covalent structure of the products and their ordering. The conformational flexibility within the chains is investigated via a comparision of room temperature and cryogenic measurements.

Study Objectives: Physicians-in-training (residents, fellows) and Advanced Practice Providers (APPs) receive limited education on sleep disorders, including obstructive sleep apnea (OSA). They often assess patients first. We aimed to understand their views on OSA and screening for OSA in the perioperative period.

Adhesion G protein-coupled receptors (aGPCRs) are expressed in all organs and are involved in various mechanobiological processes. They are heavily alternatively spliced, forecasting an extraordinary molecular structural diversity. Here, we uncovered the existence of unconventional single-transmembrane (1TM)-containing ADGRL/Cirl proteins devoid of the conventional GPCR layout (i.

It is generally accepted that a weakening of the North Atlantic thermohaline circulation caused the Younger Dryas cooling. Although the role of seasonality was emphasized previously, this aspect is rarely considered yet, and it remains elusive how this impacted hydroclimate during winters and summers across Central Europe. Here, we coupled biomarker-based δO and δH from Bergsee in southern Germany to reconstruct deuterium excess as a proxy for evaporation history from the Bølling-Allerød to the Preboreal.

Article Synopsis
- - A new trisazo dipyridyl ligand and its copper(I) complex were created and analyzed, with the complex demonstrating a unique five-coordinate geometry and effective redox activity due to its low-lying π* orbital.
- - The strong π-acceptor nature of the ligand led to an anodic Cu(II)/Cu(I) redox potential of 0.62 V, with various spectroscopic techniques and DFT calculations employed to investigate the redox events of both the ligand and the complex.
- - The ligand's ability to facilitate multiple reductions allowed for successful Glaser coupling reactions with terminal alkynes, showing that the ligand played a key role in substrate interaction and bond formation, while the metal acted mainly

We have developed a family of dinuclear complexes using 2,7-disubstituted 1,8-naphthalenediol ligands that bind by molecular recognition to two neighboring phosphate diesters of the DNA backbone with the dinuclear Cu and Ni complexes exhibiting a severe cytotoxicity for human cancer cells. To increase the binding affinity, we intended to synthesize the corresponding dinuclear Fe complex. Surprisingly, we obtained a tetranuclear Fe perylene-based complex instead of the expected dinuclear Fe naphthalene-based complex.
