This book highlights a comprehensive review of synthesis, properties, and strategies to improve the applicability of 2D materials like graphene, borophenes, metal nanosheets, phosphorene, and transition metal dichalcogenides (TMDs). It also highlights the synthesis of 2D-based hybrid composite materials and their effects on applicability, especially in energy, environment, and biomedical applications, by incorporating surface functional groups, metal/non-metal ions, and polymers. The advancement in innovative technology and use of 2D-based hybrid composite materials can improve the development of newer products/opening newer possibilities to fight existing issues related to environment, energy, and biomedical sciences. However, researchers continue to face numerous challenges in developing newer products/possibilities, large-scale production, with health and environmental impact being a challenge. This book serves as a valuable resource for researchers, professionals and students working in the field of advanced materials, especially 2D-based hybrid composites.

This thesis addresses the design of crystal structures using hydrogen bonds. In particular, it focuses on the design of functionalities and the control over the packing of molecular assemblies, based on molecular designs. Firstly, the synthesis and evaluation of a proton–electron mixed conducting charge transfer salt is reported. Focusing on the difference in the strength of hydrogen bonds and weaker intermolecular interactions, a system was rationally designed and constructed where electron-conducting molecular wires were encapsulated within a proton-conducting matrix. Next, the investigation of structural phase transitions in a cocrystal consisting of hydrogen-bonded two-dimensional molecular assemblies is reported. Drastic rearrangements of hydrogen-bonded molecular assemblies in the cocrystal led to single-crystal-to-single-crystal phase transitions, resulting in anisotropic changes in the crystal shape. Furthermore, chemical modification ofa component molecule in the cocrystal is reported. The modification afforded control over the stacking patterns of the two-dimensional molecular assemblies, i.e., sheets, and the mechanism was discussed considering the intersheet intermolecular interactions and molecular motion. It is suggested that hydrogen bonds are beneficial to construct molecular assemblies in molecular crystals because of their strength and well-defined directionality, and the consideration of coexisting weaker intermolecular interactions can lead to the design of whole crystal structures and, hence, functionalities. This thesis benefits students and researchers working on solid-state chemistry by presenting various methods for characterizing and evaluating the properties of molecular solids.

Solution-Processed Organic Light-Emitting Devices provides a comprehensive reference on the principles and advances in materials design, device structures, and processing technologies of organic light-emitting diodes (OLEDs). Most importantly, the book analyses the dynamics of thin-film growth from solutions such as solvent orthogonalization, coffee-ring effects, and interfacial adhesion. Exciton generation and utilization, host–guest energy transfer, and interfacial interaction in the solution-processed films are considered with the material and device design to maximize the electroluminescent performance of OLEDs.The book reviews the materials, devices, and technologies dedicated to solution-processed thin-film devices, which are not only applicable to OLEDs but may be adapted to other emerging semiconducting devices due to the similarity in methods (for instance, quantum-dot LEDs and solar cells, and perovskite-based LEDs/photovoltaics/detectors).This book is suitable for researchers in academia and industry working in the materials science and engineering, chemistry, and physics disciplines.
