This book was released on 2020-04-18 with total page 200 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book highlights and investigates novel solid-state luminescent properties of crystals with stimuli-responsive behavior. Several novel molecular designs for controlling crystal structures with photo-physical properties are described, with a special focus on external stimuli-responsive properties. The major goal of the material design concept was to capitalize on the chirality of crystals with stimuli-responsive properties. To allow crystals’ chirality to be controlled and modified by means of external stimulation, the axial chirality of biaryl moiety was employed and, interestingly, produced several novel mechano- and vapo-responsive luminescent properties based on crystal-to-crystal or single-crystal-to-single-crystal phase transitions. In addition, the book details how the molecular rotation of luminophores in the solid phase can be used to achieve corresponding thermal-responsive phosphorescence. The reports presented here illustrate how the author has succeeded in controlling structural factors in a bulk environment by using molecular design with linking to photo-physical properties. The content will be of great interest to researchers in the field, and to members of chemical and material science societies.

This book was released on 2011 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: Structural and spectroscopic studies of a number of two-coordinate and three-coordinate gold(I) compounds have been conducted. These studies were undertaken in order to examine various influences one aurophilic interactions, where aurophilicity is generally defined as a non-covalent, weakly attractive interaction between two gold atoms and to investigate other interesting photo-physical properties such as luminescence and vapochromism. Two- and three-coordinate gold(I) complexes discussed here, displayed structural diversity, a variety of aurophilic interactions, and interesting luminescence or vapoluminescence properties. Simple mixing of the labile complex (tht)AuBr with dppe in either dichloromethane or acetone results in the formation of a colorless product with a green luminescence that can be crystallized from a variety of solvents to produce three distinct types of colorless crystals, each of which is a solvate.: type A, orange luminescent solvates of the dimer Au2(dppe)2Br2(Au2([mu]-dppe)2 Br22(OSMe2), Au2([mu]-dppe)2Br22(OCMe2), Au2([mu]-dppe)2Br22(CH2Cl2), Au2([mu]-dppe)2Br22(HC(O)NMe2)); type B, green luminescent solvates of the same dimer (Au2 ([mu]-dppe)2Br2(NCMe) and Au2([mu]-dppe)2Br20.5(C4H10O); and type C, orange luminescent solvates of a polymer ({Au([mu]-dppe)Br}n 0.5(C4H10O) and {Au([mu]-dppe)Br}n(CH2C2). Some crystals of types A are solvoluminescent. Exposure of type A crystals of Au2([mu]-dppe)2Br22(OCMe2) or Au2([mu]-dppe)2Br22(CH2Cl2) to air or vacuum results in the loss of the orange luminescence and the formation of new green luminescent crystals. Solutions containing the components Au+, dppe (dppe is bis-(diphenylphosphino)ethane), and I- in a 1:1:1 ratio can produce five different types of crystals: type 1, orange luminescent solvates of the dimer Au2(dppe)2I2 (isostructural crystals of Au2([mu]-dppe)2I22(OSMe2), Au2([mu]-dppe)2I22(OCMe2)-[alpha], and Au2([mu]-dppe)2I22(CH2Cl2)); type 2, yellow-green luminescent solvates of the same dimer (isostructural crystals of Au2([mu]-dppe)2I22(OCMe2)-[beta]) and Au2([mu]-dppe)2I22(HC(O)NMe2)-polymorph-1); type 3, a yellow luminescent solvate containing two different molecules of the dimer Au2(dppe)2I2(Au2([mu]-dppe)2I22(HC(O)NMe2)-polymorph-2); type 4, orange luminescent crystals of the iodide-bridged dimer Au2([mu]-dppe) 2([mu]-I)2 ; and type 5, orange emitting crystals of polymeric Au2([mu]-dppe)2I22(CHCl3). Simple reactions of gold(I) with PnP, where PnP is PPh2(CH2)[n] PPh2 with n=3-6, produced seven crystalline dimers from molecules of the type, Au2([mu]-P[n]P)2X2 , where, X is bromide or iodide. The molecules show accordion-like structures (n=3, 4 for bromide and n=3, 4, and 6 for iodide) and hinge-like structures (n=5 for both bromide and iodide), which is the first three-coordinate gold complexes with non-centro symmetry. The range of Au···Au separations of these compounds are remarkably longer than other related compounds. Solutions containing the components Au+, dpae (dpae is 1,2 bis-(diphenylarsine)ethane), and X- (X is Cl, Br, or I) in a 2:1:2 ratio can produce two different forms: colorless blocks and colorless needles. Crystallographic studies of these crystals show that they are polymorphs with different motifs: polymorph [alpha] that form discrete dimers, and polymorph [beta] that assemble into polymeric chains. Cationic [Au2([mu]-dpae)2](PF6)22CHCl3 and [Au2([mu]-dpae)2](AsF6)22(CHCl3) have been also obtained from the similar reaction of either [alpha]-[Au2([mu]-dpae)X2] or [beta]-[Au2([mu]-dpae)2X2], but, with excess of KPF6 and NaAsF6. Crystallographic studies have revealed that these crystals are isostructural with close but, slightly different Au separations.

Download or read book Synthesis, Crystallization, and Characterization of Gold(I) Complexes with Studies on Luminescence, Polymorphism, and Response to Environmental Stimuli written by Phuong (Lucy) Minh Cam Luong and published by . This book was released on 2020 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: The research presented in this dissertation focuses on the synthesis, crystallization, and characterization of various gold(I) complexes. With every gold(I) crystal, intensive studies were conducted to uncover any luminescence, polymorphism, and/or response to environmental stimuli such as temperature, vapor, and pressure. All doctoral research performed in the Balch lab, including collaborations with other members as well as outside research groups, is not fully presented in this dissertation. A list of publications can be found at the end. Chapter 1 explores the role of anions and mixture of anions in crystals of bis(cyclohexylioscyanide) gold(I) cations, [(C6H11NC)2Au]+. A new crystal was synthesized and characterized with the (SbF6)− noncoordinating anion. The crystal displayed no known polymorphism unlike its previously synthesized (PF6)− and (AsF6)− analogues. However, by mixing combinations of anions and ratios of anions, an isostructural set of crystals were produced. Not only were thermochromic trends observed for mixed anion crystals with known thermochromic species but unexpected thermochromic properties appeared in mixed anion crystals that contained species with no thermochromism. In Chapter 2, the vapochromic and vapoluminescent properties of both [(C6H11NC)2Au](PF6) and [(C6H11NC)2Au](AsF6) were further investigated to uncover the first observed single-crystal-to-single-crystal phase transition, verified by single crystal X-ray diffraction, of both species. A rare case of a two-polymorph single crystal of each species was achieved as well. With no vapor molecules incorporated in these crystals, the mechanism of conversion was further examined at the macroscopic, microscopic, and atomic level to understand how these solvent-free crystals transform from solvent vapor exposure. Chapter 3 focuses on methods to isolate [(C6H11NC)2Au]+ to form non-luminescent crystals, which was achieved through bulky noncoordinating anions and solvent molecules. Newly synthesized [(C6H11NC)2Au](BArF24) was crystallized but showed no further interesting properties other than purposely isolating aurophilic interactions. However, the first solvates of these [(C6H11NC)2Au]+ series, C6H6·[(C6H11NC)2Au](AsF6) and C6H6·[(C6H11NC)2Au](SbF6), were crystallized that displayed a unique turning on of luminescence when left to dry that matched their solvent-free forms, as verified by powder X-ray diffraction, infrared spectroscopy, and fluorescence spectroscopy. Differing from the other studies, Chapter 4 examines the structure and luminescence of three-coordinate 2,2'-bipyridine gold(I) tertiary phosphine crystals. Separate isomorphic series of [(Ph3P)Au(bipy)]XF6 and [(Et3P)Au(bipy)]XF6 (where X = P, As, or Sb) along with binuclear [[mu]2-bipy(AuPPh3)2](PF6)2 were crystallized and showed no luminescence, which is unlike that of known strongly luminescent gold(I) phosphines. However, the three-coordinate [(Ph3P)Au(bipy)]XF6 and [(Et3P)Au(bipy)]XF6 complexes all displayed significantly unsymmetrical coordination of the gold(I) to the two nitrogen atoms in the 2,2'-bipyridine ligand. These large unsymmetrical distances were further investigated.
