Chem Rec. 2023 Sep 18:e202300141. doi: 10.1002/tcr.202300141. Online ahead of print.ABSTRACTElectrical conductivity is very important property of nanomaterials for using wide range of applications especially energy applications. Metal-organic frameworks (MOFs) are notorious for their low electrical conductivity and less considered for usage in pristine forms. However, the advantages of high surface area, porosity and confined catalytic active sites motivated researchers to improve the conductivity of MOFs. Therefore, 2D electrical conductive MOFs (ECMOF) have been widely synthesized by developing the effective synthetic st...

Recent Developments on Electroactive Organic Electrolytes for Non-Aqueous Redox Flow Batteries: Current Status, Challenges, And Prospects
Chem Rec. 2023 Sep 11:e202300233. doi: 10.1002/tcr.202300233. Online ahead of print.ABSTRACTThe ever-increasing threat of climate change and the depletion of fossil fuel resources necessitate the use of solar- and wind-based renewable energy sources. Large-scale energy storage technologies, such as redox flow batteries (RFBs), offer a continuous supply of energy. Depending on the nature of the electrolytes used, RFBs are broadly categorized into aqueous redox flow batteries (ARFBs) and non-aqueous redox flow batteries (NARFBs). ARFBs suffer from various problems, including low conductivity of electrolytes, inferior charge/...

Fluorescent Probes and Quenchers in Studies of Protein Folding and Protein-Lipid Interactions
Chem Rec. 2023 Sep 11:e202300232. doi: 10.1002/tcr.202300232. Online ahead of print.ABSTRACTFluorescence spectroscopy provides numerous methodological tools for structural and functional studies of biological macromolecules and their complexes. All fluorescence-based approaches require either existence of an intrinsic probe or an introduction of an extrinsic one. Moreover, studies of complex systems often require an additional introduction of a specific quencher molecule acting in combination with a fluorophore to provide structural or thermodynamic information. Here, we review the fundamentals and summarize the latest pro...

Histidine Photooxygenation Chemistry: Mechanistic Evidence and Elucidation
Chem Rec. 2023 Sep 7:e202300198. doi: 10.1002/tcr.202300198. Online ahead of print.ABSTRACTHistidine photooxygenation has been the subject of extensive investigation for many years. The intricate nature of histidine distinguishes it from other amino acids, as its side chain readily undergoes changes in charge state and tautomerization in response to pH, and the polarity of the imidazole ring inverts upon oxidation. This complexity gives rise to a diverse range of oxidation products and mechanisms, posing challenges in their interpretation. This review aims to provide a thorough overview of the chemistry involved in histidi...

Dihydroazolopyrimidines: Past, Present and Perspectives in Synthesis, Green Chemistry and Drug Discovery
Chem Rec. 2023 Sep 5:e202300244. doi: 10.1002/tcr.202300244. Online ahead of print.ABSTRACTDihydroazolopyrimidines are an important class of heterocycles that are isosteric to natural purines and are therefore of great interest primarily as drug-like molecules. In contrast to the heteroaromatic analogs, synthetic approaches to these compounds were developed much later, and their chemical properties and biological activity have not been studied in detail until recently. In the review, different ways to build dihydroazolopyrimidine systems from different building blocks are described - via the initial formation of a partiall...
