As long as chemists have marveled at the specificity of interactions in enzymes, nucleic acids, and other biological motifs that contain an inner cavity, there has been much desire to construct molecules that mimic these in function. Inspired by work performed by Charles J. Pederson on crown ethers, Donald J. Cram conducted seminal research into the construction and the host-guest interactions of a number of molecular architectures, specifically with his work on carcerands and hemicarcerands. Since Cram's early work, the field of cavitand chemistry has taken off, providing endless examples in architecture capable of enclosing the space around a guest molecule. Some common examples of artificial hosts are cryptophanes, cucurbit[n]urils, and calixaranes. Function and application vary as much as structure, and range from stabilizing reactive intermediates and probing fundamental questions in physical organic chemistry, to drug delivery and chiral separations. Meanwhile, in the Badjic Group, the development of cavitands functionalized with dynamic apertures, or gates, have allowed us to probe fundamental questions in the kinetics of encapsulation. These studies have relied upon a single symmetric host. As a result, the group has taken on the challenge of constructing new architectures giving consideration toward the inner space geometry to allow for installation of "gate" moieties onto these architectures. My research efforts have focused on the development of these new molecular architectures, with applications towards molecular recognition. Three journeys will be described, about how the key bicyclic core is transformed to give rise to differently shaped hosts. These synthetic methodologies allow for multi-gram syntheses of desired products and better potential control of their stereochemistry, all the while utilizing more environmentally friendly methodologies. Currently being explored is using these architectures for different possible applications, including studying recognition phenomena, and perhaps building chiroptical sensors capable of reporting on the presence of minute quantities of chiral substances in the environment.

The chemical sensor plays an essential role in the fields of environmental conservation and monitoring, disaster and disease prevention, and industrial analysis. A typical chemical sensor is a device that transforms chemical information in a selective and reversible way, ranging from the concentration of a specific sample component to total composition analysis, into an analytically useful signal. Much research work has been performed to achieve a chemical sensor with such excellent qualities as quick response, low cost, small size, superior sensitivity, good reversibility and selectivity, and excellent detection limit. This book introduces the latest advances on chemical sensors. It consists of 15 chapters composed by the researchers active in the field of chemical sensors, and is divided into 5 sections according to the classification following the principles of signal transducer. This collection of up-to-date information and the latest research progress on chemical sensor will provide valuable references and learning materials for all those working in the field of chemical sensors.

This fundamental book presents the most comprehensive summary of the current state of the art in the chemistry of cage compounds. It introduces different ways of how ions and molecules can be encapsulated by three-dimensional caging ligands to form molecular and polymeric species: covalent, supramolecular, and coordination capsules. The authors introduce their classification, reactivity, and selected practical applications. Because encapsulation can isolate caged ions and molecules from external factors, the encapsulated species can exhibit unique physical and chemical properties. The resulting specific reactivity and selectivity can open up a range of applications, including chemical separation, recognition, chiral separation, catalysis, applications as sensors or probes, as molecular or supramolecular devices, or molecular carriers (cargo).A particularly strong emphasis in this book is on the summary and review of the synthesis of various types of cage compounds. Readers will find over 850 literature references summarized and clearly represented in over 600 schemes and illustrations. The book is structured by the types of caging ligands (covalent, supramolecular, or coordination capsules). The authors further arranged the chapters by ligand classes and types of encapsulated species (neutral molecules, anions, or cations). Readers will hence find an exhaustive reference resource and summary of the current state of research into encapsulated species, nowadays almost a separated realm of modern chemistry.
