Chemistry of Porous Liquids: Theory, Synthesis, Simulation and Applications serves as an introduction to the emerging field of porous liquids an innovative new class of liquid porous material discovered in 2015; Given this recency, this book is the first of its kind with a focus on novel concepts within the field, including design ideas for synthesis methods, characterization means, simulation research and the latest cutting edge examples of applications relevant for research, academia and industries including discussion on the challenges, opportunities, and future directions in the study of porous liquids. Part I introduces the history and theory underpinning porous liquids, with a focus on the properties of various PLs and a thorough discussion of their relative advantages and disadvantages. This section will be invaluable to both current and future researchers by offering an understanding of this emerging field. Part II builds upon this theoretical overview, with a specific focus on design ideas for the synthesis, and subsequent classification of porous liquids. This section will support researchers to not only consider how to plan and structure their own research into this nascent field, but also crucially offer insights into how to characterise, and help validate, porous liquids once they have been synthesized. Part III of this book provides a framework for simulation studies and computational modelling of porous liquids, with machine learning as a means of optimising synthesis techniques. Part IV then considers the applications of porous liquids, offering examples such as flowing sorbents toward gas sorption and separation, membrane separation, catalysis, and a novel platform for extraction- desulfurization of fuel. This chapter also posits the real-word potential applications across various research fields weighed against a discussion of the practical considerations underpinning porous liquids. Chemistry of Porous Liquids will be an invaluable resource primarily for materials chemists, materials scientists, and chemical engineers working across the porous materials and liquid sorbent fields, providing a thorough overview of the current research on porous liquids and a comparison of the systems. It will also be invaluable to researchers who work both within and outside of materials but looking to move into the field of porous liquids, as it provides a guide to assessing the applications of porous liquids in various relevant fields whilst providing a toolkit to start planning and designing new research.
