Zeolites, with their crystalline microporous structure, are cordial hosts to a wide variety of guests. Traditional absorption techniques, as well as X-ray diffraction and spectroscopic techniques, have contributed to a better understanding of the nature of the host materials' characteristic cavities, cages and channels. The same techniques, coupled with powerful computational methods, have given new insights into the interactions of guest molecules with their hosts. In turn, this has led to new developments in the direction of structure during zeolite synthesis as well as potentially new applications of guest-host materials. The 11 chapters of Inclusion Chemistry with Zeolites: Nanoscale Materials by Design represent the cutting edge of modern research, describing some of the most recent studies on structure direction in synthesis, characterization techniques, computational aspects, coordination and organometallic chemistry, phohemistry, and electronic and optical materials. The diversity and wide utility of its presentation will inspire creative readers to create their own 'nanoscale materials by design'.
