Cryptophane Derivatives as Gas Sensors and Hyperpolarized Xenon-129 Biosensors
ABSTRACT CRYPTOPHANE DERIVATIVES AS GAS SENSORS AND HYPERPOLARIZED XENON-129 BIOSENSORS Najat S. Khan Professor Ivan J. Dmochowski This thesis describes the progress in the development of cryptophanes for three different applications: encapsulation of noble gases, 129Xe NMR biosensing for cancer …

SPECTROSCOPIC STUDIES OF NUCLEAR SPINS POLARIZED VIA SPIN EXCHANGE OPTICAL PUMPING AND DYNAMIC COUPLING IN CRYPTOPHANE HOST-GUEST COMPLEXES
… to electronic and then nuclear spins. Next, cryptophane complexes are ideal choices for fundamental studies of prototypical host-guest interactions. Of general interest when studying host-guest interactions is how (1) physical confinement at the nanoscale and (2) interactions between guest …

'Amplifying' the NMR signatures of host-guest interactions and molecular structure using liquid-crystalline matrices and polarization enhancement of nuclear spins
… the procedures for synthesizing many of the cryptophanes used in the NMR experiments in this dissertation. The cryptophanes synthesized include cryptophane-A, cryptophane-223, and cryptophane-E as well as the water-soluble derivatives of each. The eighth and ninth chapters investigate the …

Structure, Function and Applications of Metal-Requiring Enzymes: Carbonic Anhydrase and Epi-Isozizaene Synthase
Cryptophane Biosensors for Targeting Human Carbonic Anhydrase Cryptophanes represent an exciting class of xenon-encapsulating molecules that can be exploited as probes for nuclear magnetic resonance imaging. A series of carbonic anhydrase-targeting, xenon-binding cryptophane biosensors were …

NOVEL EXPERIMENTAL APPROACHES AND THEORETICAL MODELS FOR IMPROVING SENSITIVITY AND INFORMATION CONTENT OF NMR AND MRI SPECTROSCOPY
… in an effort to contribute to this field. First, cryptophanes are cage-shaped molecules that have previously been used to encapsulate molecules of interest for a number of potential applications--including gas sensing and biosensing. In one set of studies, encapsulation of molecular hydrogen gas …
