Abstract:

This thesis project has focused on the development of high-pressure single-crystal diffraction experiments on the neutron Laue diffractometer KOALA at the OPAL reactor at ANSTO, Australia. Over the course of this project several candidate systems have been studied under conditions of high-pressure using X-ray diffraction with a view to their use in developmental experiments on KOALA. The results of two high-pressure KOALA experiments are presented as well as the notable results from X-ray diffraction on the candidate systems. The first experiment on hexamethylenetetramine provided valuable ins

Abstract:

High-quality platelet single crystals of Tl₂Ba₂CuO₆±δ (Tl-2201) have been grown using a novel time-varying encapsulation scheme, minimizing the thallium oxide loss that has plagued other attempts and reducing cation substitution. This encapsulation scheme allows the melt to be decanted from the crystals, a step previously impossible, and the remaining cation substitution is homogenized via a high-temperature anneal. Oxygen annealing schemes were developed to produce sharp superconducting transitions from 5 to 85 K without damaging the crystals. The crystals' high homogeneity and high degree

Abstract:

Growing environmental concerns, coupled with increasing regulatory restrictions, are requiring industries to develop non-lead-based compositions of ferroelectric and piezoelectric materials. These materials—now widely used in sensors, actuators, and transducers—are for the most part lead-based compounds such as Pb(Zr,Ti)O3 (PZT). Indeed, PZT represents the dominant market share for use in these technologies. Moreover, next generation compounds, which include Pb(Mg1/3Nb2/3)O3-xat%PbTiO3 (PMN-x%PT) crystals with ultrahigh piezo-/electromechanical properties, are also Pb-based systems and thus ar

The boronic acid functionality interacts via intramolecular hydrogen bonds with the acetyl group and with the –B(OH)2 functionality of an adjacent molecule. The resulting centrosymmetric dimer exhibits an anti-positioning of the ferrocenyl moieties towards the central B2O4 plane. Consequently, an (Rp,Sp)-, i.e. a meso configuration is present for this dimer. In the crystal, weak C—H⋯O hydrogen bonds consolidate the molecular

Among the natural species, the majority shows an aluminosilicate framework. Two subgroups can be identified according to the extraframework content of the can units: the cancrinite- and the davyne-subgroups, showing Na-H2O and Ca-Cl chains, respectively.

The case studies show that these defect features could lead to a misinterpretation of X-ray intensity data. The structural interpretations obtained from these XSRD analyses could be significantly different when physical properties of the crystals are considered.In the second

Abstract:

Poly-aryl, also known as polyphenylene compounds are a class of dendrimer, which contain a large number of aromatic rings. They are of interest because they display restricted rotation of their stearically congested aromatic rings. These extended structures have the potential to act as precursors for even larger aromatic systems and have many applications including electronic devices, drug delivery and catalysis. A total of 23 novel poly-aryl compounds have been examined using single crystal X-ray diffraction and a number of structural patterns have emerged. Six of the compounds contain alkyne

Abstract:

碩士<br>國立中興大學<br>化學系所<br>96<br>We use (N-NHCO(o-Cl)C6H4-Htpp) to react with Tl(OAc)3 and Cd(OAc)2 and form (Tl(N-NCO(o-Cl)C6H4-tpp)(OAc)•H2O) and Cd(N-NCO(o-Cl)C6H4-tpp)(OAc)•CH2Cl2). Because (Zn(N-NCO(o-Cl)C6H4-tpp)(MeOH)) and (Zn(N-NHCO(o-Cl)C6H4-tpp)(Cl)) have been synthesized, we use 1H-1H COSY、HSQC、HMBC(heteronuclear multiple bond coherence) and DEPT to analyse the NMR data and X-ray Single-Crystal Diffractometer to determine the structure and compare the differences.

Abstract:

博士<br>中興大學<br>化學系所<br>95<br>Chapter 1 The crystal structures of Tl(tpp-N-O)(OAc) 3 and acetato-N-p-tert-butylbenzensulfonylimido-meso-tetraphenylporphyrinatothallium(III) Tl(N-p-NSO2C6H4tBu-tpp)(OAc) 5 were determined. The coordination sphere around Tl3+ is a distorted square-based pyramid in which the apical site is occupied by a bidentate chelating OAc‾ group for 3 and 5. The plane of three pyrrole nitrogen atoms [i. e., N(1), N(2), and N(3)] strongly bonded to Tl3+ in 3 and 5 is adopted as a reference plane, 3N. The porphyrin ring is severely distorted and the pyrrole ring N(4) bonding to t
