Download or read book Effects of Molecular Interactions on the Photophysical Properties of Luminescent Materials written by Maya Chaaban and published by . This book was released on 2022 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: Molecular luminescent materials have been widely studied and used in different applications, including optoelectronics, sensors, and bioimaging. The photophysical properties of these materials are controlled by several factors, such as their aggregation behaviors, molecular electronic structures, and modes of assembly. Molecular interactions, either intra- or intermolecular, play a significant role in regulating these factors. Therefore, understanding these interactions, which are unique to each material system, improves our ability to rationally design molecular luminescent materials with desired electronic and optical properties. In this dissertation, we explore the effects of molecular interactions on the photophysical properties, such as emission colors and photoluminescence quantum efficiencies (PLQEs), for two different classes of materials: cyclometalated Pt(II) complexes and organic metal halide hybrids. Cyclometalated Pt(II) complexes adopt a square-planar geometry that favors their assembly through Pt-Pt interactions. These complexes are known to display very distinguished photophysical properties depending on the level of interactions between the Pt centers. They can either exhibit emissions from the high energy ligand centered/metal-to-ligand charge transfer (LC/MLCT) state or the lower energy metal-to-metal-ligand charge transfer (MMLCT) state. In binuclear Pt(II) complexes, the Pt centers are bridged by an appropriate bridging ligand (e.g., pyrazole) which dictates their molecular geometries. Chapter 2 and 3 of this dissertation discuss binuclear Pt(II) complexes with H-frame and A-frame geometries, respectively. In Chapter 2, the synthesis and characterization of a series of binuclear 2,4-difluorophenylpyridine Pt(II) complexes bridged by thiazol-2-thiolate ligands with different bulkiness are reported. The three complexes adopt H-frame geometries or half-lantern structures with short Pt-Pt distances ranging from 2.916 to 2.945 Å, favoring their intramolecular Pt-Pt interactions. All these complexes are found to exhibit strong and stable 3MMLCT emissions in the orange/red region, with PLQEs reaching near-unity. Chapter 3 covers another series of binuclear Pt(II) complexes that have no intramolecular Pt-Pt interactions due to their A-frame geometries and long Pt-Pt distances. These complexes are bridged by pyrazole and have different cyclometallating ligands (N,N-dimethyl-3-(pyridin-2-yl)aniline and 2-(naphthalen-1-yl)pyridine). The complex with N,N-dimethyl-3-(pyridin-2-yl)aniline as its cyclometallating ligand exhibit a positive solvatochromic behavior introduced by the electron-donating dimethylamino group. This behavior is studied in several solvents with different polarities and evaluated using the Lippert-Mataga correlation and the empirical solvent polarity parameter ET(30). The positive solvatochromism recorded for this complex is assigned to the intramolecular charge transfer character of its emission. In addition to binuclear Pt(II) complexes, mononuclear cationic Pt(II) complexes are studied in Chapter 4. Intermolecular Pt-Pt interactions can exist between these complexes, which are regulated in a series of four mononuclear cationic Pt(II) complexes by modifying their counter-anions and molecular structures. These complexes exhibit strong 3MMLCT emissions in solid state with colors ranging from green to deep red. The structural and photophysical characterizations of these complexes reveal a clear correlation between their stacking modes and photophysical properties. The second class of materials studied in this dissertation is the ionically bonded organic metal halide hybrids. The remarkable structure diversity of this class of materials, originating from the infinite combinations of organic cations and metal halides, unlocks many new properties of both components. In Chapter 5, the synthesis and characterization of a series of benzoquinolinium (BZQ+) metal halides with a unique two-dimensional (2D) structure are reported. The structures are composed of layers of face-sharing metal halides (Pb2X5-, X= Cl, Br) separated and balanced by cationic BZQ+ arrays. The BZQ+ cations are found to be responsible for the emission of these hybrid materials, as revealed by their optical characterizations and theoretical calculations. The inorganic layers in the 2D structure scaffold the organic cations and provide a more rigid architecture due to stronger molecular interactions, enhancing the PLQEs and stability of the BZQ+ cations in the 2D metal halide hybrids compared to the pristine BZQ halides. In addition to the scaffolding effect, the composition of metal halide also affects the photophysical properties of BZQ+ cations. Replacing Cl by the heavy atom Br results in room temperature phosphorescence (RTP) from cationic BZQ+ due to heavy atom effects.

This book was released on 2015-06-30 with total page 266 pages. Available in PDF, EPUB and Kindle. Book excerpt: The series Structure and Bonding publishes critical reviews on topics of research concerned with chemical structure and bonding. The scope of the series spans the entire Periodic Table and addresses structure and bonding issues associated with all of the elements. It also focuses attention on new and developing areas of modern structural and theoretical chemistry such as nanostructures, molecular electronics, designed molecular solids, surfaces, metal clusters and supramolecular structures. Physical and spectroscopic techniques used to determine, examine and model structures fall within the purview of Structure and Bonding to the extent that the focus is on the scientific results obtained and not on specialist information concerning the techniques themselves. Issues associated with the development of bonding models and generalizations that illuminate the reactivity pathways and rates of chemical processes are also relevant. The individual volumes in the series are thematic. The goal of each volume is to give the reader, whether at a university or in industry, a comprehensive overview of an area where new insights are emerging that are of interest to a larger scientific audience. Thus each review within the volume critically surveys one aspect of that topic and places it within the context of the volume as a whole. The most significant developments of the last 5 to 10 years should be presented using selected examples to illustrate the principles discussed. A description of the physical basis of the experimental techniques that have been used to provide the primary data may also be appropriate, if it has not been covered in detail elsewhere. The coverage need not be exhaustive in data, but should rather be conceptual, concentrating on the new principles being developed that will allow the reader, who is not a specialist in the area covered, to understand the data presented. Discussion of possible future research directions in the area is welcomed. Review articles for the individual volumes are invited by the volume editors. Readership: research scientists at universities or in industry, graduate students Special offer For all customers who have a standing order to the print version of Structure and Bonding, we offer free access to the electronic volumes of the Series published in the current year via SpringerLink.

Book excerpt: Photochemistry (a term that broadly speaking includes photophysics) is abranchofmodernsciencethatdealswiththeinteractionoflightwithmatter and lies at the crossroadsof chemistry, physics, and biology. However, before being a branch of modern science, photochemistry was (and still is today), an extremely important natural phenomenon. When God said: “Let there be light”, photochemistry began to operate, helping God to create the world as wenowknowit.Itislikelythatphotochemistrywasthesparkfortheoriginof life on Earth and played a fundamental role in the evolution of life. Through the photosynthetic process that takes place in green plants, photochemistry is responsible for the maintenance of all living organisms.

Photochemistry as a science is quite young; we only need to go back less than one century to ?nd its early pioneer [1]. The concept of coordination compound is also relatively young; it was established in 1892, when Alfred Werner conceived his theory of metal complexes [2]. Since then, the terms coordination compound and metal complex have been used as synonyms, even if in the last 30 years, coordination chemistry has extended its scope to the binding ofall kinds of substrates [3, 4].
