題目:From Cationic Helical Derivatives to Metal-Free and Metal-Bound Ylide Chemistry
LinkIconinformation

Abstract: Carbenes are electrically neutral low-valent forms of carbon that are highly reactive when substituted with strong electron-withdrawing groups. These electrophilic species react well with Lewis bases to generate ylide intermediates. We demonstrated the chemical structure and reactivity of oxonium, ammonium, and carbonyl ylides.1–4 A large array of original transformations and structures are generated in a single step. Triaryl-substituted carbenium ions (carbocations) are important building blocks, readily prepared from simple precursors and presenting a large panel of tunable geometrical, chemical and physical properties. We developed short and highly modular syntheses and the use of functionalized triangulenes, [4]helicenes, and [6]helicenes.5–10 In particular, the helicene derivatives present helical geometries with very high barriers of racemization between enantiomers. The chemical, (chir)optical, and photophysical properties are characterized and applied to questions in chemistry, biology, and physics.

題目:Colored Titanium Oxo-Clusters
LinkIconinformation

Abstract:
Titanium dioxide (TiO2) is a cheap non-toxic semiconductor, which elicits a major interest for applications in photocatalytic water splitting,1 photocatalytic degradation of pollutants2 or solar energy conversion.3 However, TiO2 mainly absorbs the UV light due to its high band gap (3.2 eV). Therefore, to develop more practical TiO2-based photo-active materials, the researches are focused on materials that can absorb light in the visible domain. Titanium oxo-clusters4 are fascinating models of the bulk TiO2, and the intensive researches are devoted to the synthesis of polyoxotitanium complexes absorbing light in the visible region. In that context, we will describe our approach leading to an unprecedented family of colored oxo-clusters formed by a Ti10O12 inorganic core that is decorated by eight catecholato ligands and eight labile substituted pyridine ligands.5 The compound formulated as Ti10O12(cat)8(py)8 (py: pyridine; cat: catecholato) is an efficient nano-building block to generate colored hybrid materials in the presence of poly(4-vinylpyridine). The homogeneity of the resulting material and the functionalization of surfaces with oxo-cluster-based thin films will also be presented.

題目:Controlling and Driving Molecular Processes with Light

要旨: Controlling molecular building blocks and their organization into nanostructured materials with specific functions constitutes the basis of modern bottom-up materials science. Using an external light stimulus to control such advanced materials in a dynamic fashion with superior spatial and temporal resolution offer tremendous opportunities and is at the heart of our group’s research program. This presentation will highlight some recent examples from our laboratory in which carefully designed photoswitches with improved performance have been exploited to remote-control materials, specifically, some of our recent efforts to optimize various photoswitches, such as azobenzenes, diarylethenes, acylhydrazones, and indigos with regard to their switching characteristics and the use of these optimized photochromic building blocks to control dynamic polymeric materials as well as charge transport in optoelectronic devices and to drive optomechanical transduction.

題目:1,2,5-Chalcogenadiazoles as effective electron acceptors: reduction into Radical-anions vs. formation of charge transfer complexes
要旨:: 1,2,5-chalcogenadiazoles are of particular interest to the fundamental chemistry and its applications in materials science and biomedicine. The common property of heterocycles of this family is high positive electron affinity, which means these compounds are effective electron density acceptors. Chemical reduction (complete charge transfer) of the neutral 1,2,5-chalcogenadiazoles derivatives with various reducing agents yields thermodynamically stable Radial-Anions (RA), isolated in the form of thermally-stable salts. These RAs may be considered as promising building blocks for the synthesis of molecular based magnetic materials. Meanwhile, interaction with other electron donors such as TTF or certain anions (X–) results in formation of neutral or anionic charge transfer complexes (partial charge transfer). The former shows some potential for the photovoltaic applications. The latter are formed via coordination of X– to the chalcogen atom of heterocycle which leads to the changes in absorption spectra. This may be useful for the anion receptors/sensors applications. This talk will cover these two aspects of the redox reactivity of 1,2,5-chalcogenadiazoles with regards to their application.

題目:Hydrothermal and Solvothermal Synthesis for Composite Nanomaterials Preparation
LinkIconinformation

Abstract:
Nanocomposites have attracted a huge amount of interest due to their improved mechanical properties, dimensional stability, thermal/chemical stability, and electrical conductivity. Nanostructures are found to be of great significance because of their inherent properties such as large surface area to volume ratio and the engineered properties such as porosity, stability, and permeability. Composite material can achieve multifunctionality by combining the relevant, desirable features of different materials to form a new material having a broad spectrum of desired properties. Composite nanomaterials have been prepared by several techniques including sol-gel, precipitation, spray pyrolysis, hydrothermal, and solvothermal. In this presentation, hydrothermal and solvothermal techniques will be performed for preparation of CeO2-ZrO2 and ZnO-SiO2 nanocomposites because these techniques require simple equipment and easily controlled particle size and morphology by varying the synthesis conditions. The fabricated CeO2-ZrO2 nanocomposites with certain compositions could enhance their chemical and thermal properties to be used as electrolyte of Solid Oxide Fuel Cells. ZnO-SiO2 nanocomposites fabricated by solvothermal synthesis increased their chemical and optical properties for energy saving.
