This Collection aims to present the latest progress in the synthesis, characterization, functionalization, self-assembly, and applications of atomically-precise nanomaterials. It is also our intention for the Collection to highlight ongoing challenges and opportunities that such nanomaterials present, allowing us to press forward in nanoscience and nanotechnology. We welcome both experimental and theoretical studies.

Recent years have seen a rapid acceleration of research on framework materials, including, among others, metal–organic frameworks, covalent organic frameworks, supramolecular organic frameworks, porous organic polymers, and inorganic framework materials. This Collection brings together research focused on advanced characterization and computational modelling, providing new molecular insight on the structure and behaviour of framework materials.

The electrochemical reduction of carbon dioxide (CO2) is a key technology to combat global climate issues. By utilizing renewable energy, we can convert greenhouse gases into value-added commodity chemicals. While there has been a growing number of CO2 research in recent years, there are still many unanswered fundamental questions and engineering challenges. With this collection, we encourage scientists from different academic backgrounds to explore these remaining challenges in the CO2 electrochemical reduction reaction and provide a forum for the CO2 community to share their latest research results. We welcome all submission of original research articles, reviews and perspectives related to the theme of CO2 electrocatalytic reduction.

This Collection aims to present the latest progress in the chemoenzymatic syntheses of high-value-added organic compounds. We welcome both experimental and theoretical studies.

Chemistry has always had a central role in the provision of food and energy, materials and medicines. Recent years have increasingly seen chemistry research move towards environmentally friendly, sustainable products and processes.

This Guest Edited Collection aims to bring together research at the intersection of systems chemistry and coacervation. We welcome both experimental and theoretical studies.

Communications Chemistry is celebrating five years of publishing. To mark the occasion, the Editors have put together a Collection of articles from the last five years, celebrating some of the most talked about, most downloaded and most highly-cited content published in the journal.

Recognizing the potential of and ongoing intense research in aqueous zinc-based batteries, the editors of Nature Communications, Communications Chemistry and Communications Materials welcome submissions of primary research demonstrating significant development in all areas of aqueous zinc-based batteries from key element design and fundamental understanding to integrated battery systems.

To mark the International Day of Women and Girls in Science, the Editors of Communications Chemistry are pleased to launch a Collection celebrating women in chemistry, showcasing excellent research from women corresponding authors who have recently published in the journal. The Collection also includes articles focused on promoting gender equity in STEM.

This Collection aims to bring together the latest progress in the synthesis, characterization, and functionalization of covalently bonded nanomaterials fabricated by the on-surface synthesis approach, as well as highlighting advances in the synthesis of coordination polymers, macrocycles and other compounds obtained on surfaces.

In spite of decades of research and the enormous progress made, chemists continue to grapple with poorly understood aspects of the world around us. This collection aims to uncover open questions across the breadth of the chemical sciences. Each Comment provides an overview of a focused field of research, identifies key open questions, and gives expert opinion on how challenges in answering these questions might be overcome.

The Editors and Editorial Board of Communications Chemistry are pleased to launch an Editors’ Highlights Collection featuring some of their favourite Articles published in the journal in 2022. Our Editorial within outlines why each Article was selected.
