Such photons, particularly in the red and near-infrared wavelength ranges, can penetrate tissue deeply and undergo less competitive absorption in coloured reaction media, enhancing the efficiency of large-scale reactions and in vivo phototherapy. Among various upconversion methodologies, the organic-based triplet–triplet annihilation upconversion (TTA-UC) stands out — demonstrating high upconversion efficiencies, requiring low excitation power densities and featuring tunable absorption and emission wavelengths. These factors contribute to improved photochemical reactions for fields such as photoredox catalysis, photoactivation, 3D printing and immunotherapy. In this Review, we explore concepts and design principles of organic TTA-UC-mediated photochemical reactions, highlighting notable advancements in the field, as well as identify challenges and propose potential solutions. This Review sheds light on the potential of organic TTA-UC to advance beyond the traditional photochemical reactions and paves the way for research in various fields and clinical applications. Organic-based triplet–triplet annihilation upconversion-mediated photochemical reactions utilize low-energy photons to obtain high-energy excited states leading to notable advancements in photoredox catalysis, photoactivation, 3D printing and immunotherapy. Classifications, design principles, challenges and possible solutions are discussed in this Review.","PeriodicalId":18849,"journal":{"name":"Nature reviews.

Recent progress in the field has relied on advances in synthetic host design to afford a broad range of potent recognition motifs and novel supramolecular structures capable of effective binding both in solution and at derived molecular films. However, performance in aqueous media remains a critical challenge. Understanding the effects of bulk and local solvent on anion recognition by host scaffolds is imperative if effective and selective detection in real-world media is to be viable. This Review seeks to provide a framework within which these effects can be considered both experimentally and theoretically. We highlight proposed models for solvation effects on anion binding and discuss approaches to retain strong anion binding in highly competitive (polar) solvents. The synthetic design principles for exploiting the aforementioned solvent effects are explored. Anion recognition in competitive, aqueous media remains a critical challenge. Bulk and local solvation models for anion recognition events are herein explored, as well as targeted design approaches to retain strong anion binding in highly polar media.","PeriodicalId":18849,"journal":{"name":"Nature reviews.

Classically, hydrogenations are carried out on Pd, Pt, Ru or Ni catalysts. However, the use of supported Au catalysts has garnered attention in recent years owing to their exceptional selectivity in hydrogenation reactions. This is despite the limited understanding of the physicochemical aspects of hydrogen activation and reaction on Au surfaces. A rational design of new improved catalysts relies on making better use of the hydrogenating properties of Au. This Review analyses the strategies utilized to improve hydrogen–Au interactions, from addressing the importance of the Au particle size to exploring alternative mechanisms for H2 dissociation on Au cations and Au–ligand interfaces. These insights hold the potential to drive future applications of Au catalysis. Gold catalysts have attracted attention for their ability to activate hydrogen towards the hydrogenation of organic molecules. This Review explores strategies to enhance hydrogen–gold interactions to help design new efficient hydrogenation catalysts.","PeriodicalId":18849,"journal":{"name":"Nature reviews.

Many experimental techniques have been developed to probe the EI, but they provide only a partial picture. Building a full mechanistic understanding requires combining multiple probes, either successively or simultaneously. However, such combinations lead to important technical and theoretical challenges. In this Review, we focus on complementary optoelectronic probes and modelling to address the EI across different timescales and spatial scales — including mapping surface reconstruction, reactants and reaction modulators during operation. We discuss how combining these probes can facilitate a predictive design of the EI when closely integrated with theory. Electrochemical devices enable clean energy technologies such as hydrogen cells, batteries and solar fuels. Their design is hindered by incomplete information about the electrochemical interface during operation. Complementary optoelectronic probes offer a path to improved mechanistic insights into such interfaces.","PeriodicalId":18849,"journal":{"name":"Nature reviews.
