The hybridization of short nucleic acid strands is a remarkable spontaneous process that is foundational to biotechnology and nanotechnology and plays a crucial role in gene expression, editing and DNA repair. Decades of research into the mechanism of hybridization have resulted in a deep understanding of its thermodynamics, but many questions remain regarding its kinetics and dynamics. Recent advances in experiments and molecular dynamics simulations of nucleic acids are enabling more direct insight into the structural dynamics of hybridization, which can test long-standing assumptions regarding its mechanism. In this Review, we summarize the current state of knowledge of hybridization kinetics, discuss the barriers to a molecular description of hybridization dynamics, and highlight the new approaches that have begun uncovering the dynamics of hybridization and the duplex ensemble. The kinetics and dynamics of hybridization are highly sensitive to the composition of nucleic acids, and we emphasize recent discoveries and open questions on the role of nucleobase sequence and chemical modifications. This Review summarizes the current state of knowledge of DNA and RNA oligonucleotide hybridization kinetics, discusses new insights into the dynamics of hybridization and the duplex, and highlights strategies to probe hybridization at a deeper molecular level.

Lead halide perovskites (LHPs) have shot to prominence as efficient energy-conversion materials that can be processed using cost-effective fabrication methods. A reason for their exceptional performance is their crystallographic defect tolerance, enabling long charge-carrier lifetimes despite high defect densities. Achieving defect tolerance in broader classes of materials would impact on the semiconductor industry substantially. Considerable efforts have been made to understand the origins of defect tolerance, so as to design stable and nontoxic alternatives to LHPs. However, understanding defect tolerance in LHPs is far from straightforward. This Review discusses the models proposed for defect tolerance in halide perovskites, evaluating the experimental and theoretical support for these models, as well as their limitations. We also cover attempts to apply these models to identify materials beyond LHPs that could exhibit defect tolerance. Finally, we discuss the experimental methods used to understand defects in mixed ionic–electronic conductors, as well as the important information that is necessary for a deeper understanding, in order to develop improved models that enable the design of defect-tolerant semiconductors. Defect tolerance is a key factor behind the exceptional optoelectronic properties of lead halide perovskites, but it is not well understood. This Review discusses the models for defect tolerance and what has been learnt in generalizing these models to lead-free, stable materials.

Supramolecular chemistry provides a range of ‘weak’ intermolecular interactions that allow drugs and prodrugs to self-assemble. In the complex biological setting of blood and tumours, these interactions must be stable enough for efficient and selective drug delivery to the tumour site, but weak enough to allow the release of the cytotoxic load. The non-covalent nature of supramolecular interactions enables the detachment of smaller (pro)drug monomers that can penetrate cancer cells differently to the original nanoparticles. Hypoxic tumours show low oxygen levels due to poor vascularization, which poses challenges for drug delivery and generates biological resistances. Supramolecular building blocks specifically designed for hypoxic tumours offer targeted activation of prodrug self-assemblies, enhancing effectiveness against hypoxic cancer cells and hypoxic regions in tumours. This Review explores how supramolecular chemistry can improve (pro)drug delivery and activation in hypoxic tumours. Hypoxic tumours present considerable challenges in cancer treatment owing to their specific chemistry, biology and physics, which leads to resistances to conventional therapies. This Review explores innovative strategies based on supramolecular chemistry to overcome these obstacles and discusses future research directions that might help translating supramolecular approaches to the clinics.

Thermoelectric materials offer unique opportunities to convert otherwise wasted thermal energy into useful electrical energy. Many of the traditional thermoelectric materials, such as bismuth telluride and lead telluride, contain scarce and toxic elements. This has motivated the search for new high-performance materials containing readily-available and environmentally-less-damaging elements. Numerous advances in the development of high-performance thermoelectric materials exploit fundamental chemical-bonding principles. Much of the thermoelectric literature lies at the interface of chemistry, physics and materials science. In this Review, progress in the design of high-performance materials is discussed in terms of ideas that are familiar in chemistry. This includes the influence of concepts such as bonding heterogeneity, covalency, polarizability, lone pairs and different bonding models, including multi-centre, metallic and iono-covalent archetypes. In this way, we seek to present aspects of this diverse field of research in terms that are accessible to the chemistry community. Many of the advances in high-performance thermoelectric materials can be related to fundamental chemical-bonding principles. Application of concepts including bonding models, lone pairs, bonding heterogeneity, multi-centre bonding and polarizability to the development of advanced thermoelectric materials are discussed here.

Natural photosynthesis represents the pinnacle that green chemistry aims to achieve. Photocatalysis, inspired by natural photosynthesis and dating back to 1911, has been revitalized, offering promising solutions to critical energy and environmental challenges facing society today. As such, it represents an important research avenue in contemporary chemical science. However, single photocatalytic materials often suffer from the rapid recombination of photogenerated electrons and holes, resulting in poor performance. S-scheme heterojunctions have emerged as a general method to enhance charge transfer and separation, thereby greatly improving photocatalytic efficiencies. This Perspective delves into the electron transfer dynamics in S-scheme heterojunctions, providing a comprehensive overview of their development and key characterization techniques, such as femtosecond transient absorption spectroscopy, in situ irradiated X-ray photoelectron spectroscopy and Kelvin probe force microscopy. By addressing a critical research gap, this work aims to trigger further understanding and advances in photo-induced charge-transfer processes, thereby contributing to green chemistry and the United Nations sustainable development goals. This Perspective presents the developments of S-scheme heterojunctions, including their origin, formation mechanism, material design, driving forces for charge-carrier transfer, application and future developments. In particular, it introduces the characterization methods used to study ultrafast charge-transfer dynamics.
