This book covers major classes of crystals in the design of novel materials, with an emphasis on advances and applications. The editor is one of the pioneers in the "design" and "engineering" approach in solid state supramolecular chemistry All authors developed a specific class of crystals and are world leaders in the field Reflects the rapid progress made in this field.
