This book provides insight into the latest developments in the research on liquid crystals formed by bent-core mesogens. After a short historical introduction, the authors discuss different kinds of mesophase structures formed by bent-core molecules. A majority of this book is devoted to physical properties such as elasticity, optics and non-linear optics, and behavior in restricted geometries. As chemistry is often relevant to the emergence of new phases, particularly with chiral symmetry breaking, chemistry viewpoints are broadly involved in this book.
