Numerous fabrication methods have been developed so far for the production of graphenes and nanographenes. However, how practical is the bulk production of these fascinating materials? This Perspective discusses recent advances in graphene fabrication and possibilities for translation to large-scale production.
Metal–ligand cooperative catalysis involves both the metal and the ligand moieties present in a complex interacting with substrates. Cooperative catalysis is central to the mechanisms of hydrogenases, lactate racemase and alcohol dehydrogenase. This Perspective describes these enzymes, as well as the small-molecule mimics inspired by these elaborate natural catalysts.
Light-driven artificial molecular switches and motors afford dynamic control of various molecular systems, ranging from catalytic to biological. This Perspective provides insight into the challenges that must be addressed to transition the field from the proof-of-concept stage to realization of its myriad applications.
Blue energy can be cleanly and renewably harvested from a salinity gradient. The large-scale viability of this non-intermittent source is restricted by certain challenges, including the inefficiency of present harvesting technologies. This Perspective describes how nanofluidics can afford membranes better able to convert chemical potentials to electrical potentials.
Reviewing the applications of a solvent would ordinarily be an unusual thing to do, but the unique properties of hexafluoroisopropanol and its applications across a huge swathe of chemistry make that both a viable and interesting undertaking.
Redox reactions related to renewable energy challenges can be mediated by molecular electrocatalysts. Intelligent design of these catalysts calls for systematic catalyst benchmarking. This Perspective presents examples of analysing catalytic Tafel plots, noting through-structure and through-space effects on the performance and mechanism. This approach is preferred to oversimplifications inherent in using volcano plots.
The unusual electronic characteristics of boron atoms lead boron clusters to adopt a wide variety of structural arrangements, most of which are 2D. This Perspective discusses the possibility of expanding the range of boron-based 2D structures by metal doping, as well as the use of the resulting clusters for conceptualizing metalloborophenes.
The unique properties of ferrocene-containing compounds make them useful for treating many diseases. The most notable drug candidates — the antimalarial ferroquine and the anticancer agent ferrocifen — have been studied for more than two decades but have not yet met clinical approval. This Review describes the design of ferrocene-containing drugs as well as the challenges faced in bringing them into clinical use.
The cross-electrophile coupling approach to stereocontrolled C–C bond formation provides a complementary alternative to traditional cross-coupling methods. This Perspective provides an overview of the recent development of nickel-catalysed asymmetric cross-electrophile coupling reactions. Both stereoconvergent and stereospecific examples are considered and mechanistic details are highlighted.
Bis(β-diketiminato)dimagnesium(I) complexes are low-valent reagents that can each deliver two electrons in a selective and stoichiometric manner. Easily handled and dissolved, these species effect reduction of many inorganic and unsaturated organic substrates. This Perspective covers the development of magnesium(I) dimers and the scope of their reactivity.
Covalent organic frameworks (COFs) have potential applications in, for example, gas storage and separation. The pore sizes in these materials are tunable by selection of the building blocks, and materials with multiple pore sizes are desirable. This Perspective considers synthetic approaches to 2D COFs that rely on tessellation to prepare such multiporous materials.
Quadruplex DNA structures were first observed more than 50 years ago, but have only relatively recently attracted interest for their role in the development of cancer. This Perspective considers attempts to selectively bind and stabilize these structures using small molecules, with the aim of developing anticancer therapeutics.
The technological progress made since the industrial revolution has brought with it one of our greatest challenges: how to power our world while also minimizing environmental harm. This Perspective highlights the important role that quantum chemistry has in sustainable energy research.
Laboratory studies of natural product biosynthesis often focus on a particular secondary metabolite that is produced by a single species. This Perspective article considers examples in which bacteria and hosts work in concert to produce hybrid natural products.
Recent developments in systems chemistry have shown how the molecular building blocks of life could have arisen from plausible prebiotic feedstocks. This Perspective argues that we remain a long way from a full picture and speculates on what pieces of the puzzle are still missing.
