This book was released on 2020 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: This text includes multiple interconnected projects that explore the chemistry of gold(I) phosphine complexes for purposes of elucidating the interactions of monovalent gold centers both with and without aurophilic attractions. These studies expressly focus upon the solid state properties, where structural determination via X-ray crystallography is key. The first chapter focuses on the series of complexes Au2([mu]-dppe)X2 (dppe is 1,2-bis(diphenylphosphino)ethane, X = Cl, Br, I) and Au2([mu]-dcpe)X2 (where dcpe is 1,2-bis(dicyclohexylphosphino)ethane). Previous work had focused on luminescent characteristics of similar complexes, but the phosphine ligands contained fluorophoric phenyl moieties that could be identified as contributors to this phenomenon. In addition, prior comparable studies had similar ligands that displayed a propensity towards polymeric or pseudo-polymeric structures, and the increased steric bulk of cyclohexyl groups was utilized to inhibit the formation of such aggregation. This study clarifies and infers the innocent nature of the dppe ligand with regards to luminescence displayed in monovalent gold complexes containing aurophilic interactions, allowing the emissions to be more confidently attributed to the metal-metal interactions. The second chapter focuses on the synthesis and interconversion of a series of complexes comprised of triphos (bis(2-diphenylphosphinoethyl)phenylphosphine), bridging monovalent gold atoms, and non-coordinating anions. Helicate ([Au3(Triphos)2]3+) systems may form monomeric units, or dimerize with bridging chloride anions, but do not display tendencies towards polymeric formations. Gold box systems ([Au6(Triphos)4Cl]5+) may form with EF6− type anions, with a complex packing structure displaying a fascinating dependency upon cavity occupancy on the molecule's surface as well as its interior. Each of these systems display distinct luminescence and these may be readily interconverted through mechanical stimuli or a recrystallization that is sensitive to specific solvent systems. The third chapter focuses on a series of complexes analogous to those in the second chapter, but utilizing bromide ions in the places previously occupied by chloride. The same helicate,bridged dimer, and gold box interconversions are observed, with the additional possibility of a second encapsulated bromide anion. These systems display much more selective luminescence with greater diversity, and mechanical stimuli resulted in the observation of transformation through negative mechanochromism where the previous case was positive mechanochromism. The box moieties and their transitions appear to be dictated by localized interactions with anions and solvent resting within nested formations of phenyl rings. Within these studies, the box has been identified as a viable luminescent molecular container for small anions with the assistance of appropriately sized solvent molecules (e.g. toluene), but the di-bromo box system implies a greater variation for content size. A system of such extreme lability and fluxionality may have excellent potential as a selective capture agent, especially with such simplistic conformation away from a container room temperature mechanical grinding at room temperature or dissolving in a solvent that inhibits box formation such as methanol.

Abstract: Abstract of thesis entitled LUMINESCENT PLATINUM(II) COMPLEXES CONTAINING DIANIONIC TETRADENTATE LIGANDS HAVING MIXED OXYGEN, NITROGEN AND CARBON DONOR ATOMS AND PLATINUM(II)-CONTAINING PHOSPHORESCENT POLYMERS: SYNTHESIS, PHOTOPHYSICAL PROPERTIES AND MATERIAL APPLICATIONS Submitted by TONG WAI YIP for the degree of Doctor of Philosophy at The University of Hong Kong in May 2014 Square planar platinum(II) complexes exhibit rich photophysical properties which are tunable through the structural variation of ligands and can be harnessed for applications in materials science. In this thesis, the great variety of spectroscopic properties of various square planar cyclometalated platinum(II) complexes supported by tetradentate (O DEGREESN DEGREESN DEGREESC and O DEGREESN DEGREESC DEGREESN) and tridentate (C DEGREESN DEGREESN) ligands containing dipyridyl moieties will be highlighted, along with their synthesis, characterization and potential application in organic light emitting diodes (OLEDs). Ind Platinum(II) complexes supported by tetradentate O DEGREESN DEGREESN DEGREESC or O DEGREESN DEGREESN DEGREESC types of ligands (O DEGREESN DEGREESN DEGREESC = 2-(4-(3,5-di-tert-butylphenyl)-6'-phenyl-2,2'- Ind bipyridin-6-yl)phenolate; O DEGREESN DEGREESN DEGREESC = 5,5-dialkyl-2-(6-phenylpyridin-2-yl) indeno[1,2-b]pyridin-9-olate) are emissive in solution at room temperature, with emission maxima tunable from 582 nm to 640 nm and quantum yields up to 0.28. Mechanochromism and the associated luminescence change in [Pt(dihexyl- Ind O DEGREESN DEGREESN DEGREESC)] (Complex 3.6) were found associated with the two different crystal packings revealed by powder X-ray diffraction (PXRD) studies. Fast vapochromic response of [Pt(3-O DEGREESN DEGREESN-2,6-difluoropyridine)] (Complex 3.3) on chloroform or dichloromethane vapours was found to be associated with structural changes in the solid state through PXRD studies. Robust and strongly emissive platinum(II) complexes supported by tetradentate O DEGREESN DEGREESC DEGREESN ligands featuring fused six-five-six membered metallacyclic ring (O DEGREESN DEGREESC DEGREESN = 2-(4-(3,5-di-tert-butylphenyl)-6-(9-(pyridin-2-yl) carbazol-2-yl)pyridin-2-yl)phenol) have been prepared. These platinum(II) complexes are among the most efficient yellow phosphors, with emission maxima ranging from 526 nm to 553 nm and luminescence quantum yields as high as -1 0.47-0.86. A yellow OLED with power efficiency (η ) up to 52 lm W is power demonstrated. In combination with the typical blue emitting iridium(III) 2' bis(4,6-difluorophenyl-pyridinato-N, C ) picolinate (FIrpic), white organic -1 light-emitting diodes (WOLEDs) displayed η up to 61 lm W and reduced power -2 efficiency roll-off at 1000 cd m . Random copolymers with photo-inert backbone poly[(N-vinylcarbazole)-co- ((R-C DEGREESN DEGREESN)Pt)] and poly[(2-(4-tert-butylphenyl)-5-(4-vinylphenyl)-1,3,4- oxadiazole)-co-((R-C DEGREESN DEGREESN)Pt)] (R-C DEGREESN DEGREESN = 3-(6-phenyl-4-(4-vinylphenyl) pyridine-2-yl)-isoquinoline or 3-(4-(4-(dec-9-enyloxy)phenyl)-6-phenylpyridin- 2-yl)isoquinoline) have been synthesized and characterized. Energy transfer between the charge transporting units and emissive (R-C DEGREESN DEGREESN)Pt units was revealed through ICP-MS inve

This book was released on 2018-01-31 with total page 730 pages. Available in PDF, EPUB and Kindle. Book excerpt: This title takes researchers in as well as out of the field of metal-organic framework (MOF) and then guides them on a journey to rediscover and rethink how these designer coordination polymers will influence the realm of materials science. This book opens with a look at a deeply controversial issue, MOF stability, which has plagued many systems, but ultimately has led to better materials that proved to be more robust allowing them to be investigated for multiple applications. This book successfully highlights many of these useful applications that MOFs are well adapted for. Because MOF components, inorganic and organic, can combine the best of both chemical domains, MOFs will improve our environment by removing harmful contaminants from the air and water, reduce the energy required to perform chemical reactions, partition hard to separate molecular mixtures, and form the next-generation of magnetic and electronic materials. MOFs will eventually be used for everyday activities — for monitoring or reacting to changing conditions. Readers of this book can then take note and implement MOFs in their line of research.
