    Abstract

    Sulfur-rich polyaromatic architectures: asterisks, dendrimers, polymers, and their metal interactions Sulfur-rich polyaromatic architectures of various topologies will be presented, along with their synthesis, their opto-electronic properties and some applications in chemical-biology, in materials science and in nanoscience. They comprise asterisks, dendrimers, polymers and helicenes, which often incorporate a thiophenylene or a polyaromatic unit, leading to some molecular rigidity and restricted degrees of freedom. They represent an underexploited class of macromolecules with multivalent and attractive features for exalting supramolecular interactions, chiroptical and electronic properties. The latter features could be modulated from the coordination of divalent sulfur atoms to thiophilic metallic species, from some cation-? interactions, and from some ?-? complexes. Additionally, polysulfuration often enhances some electronic, photophysical and biophysical properties, leading to exalted luminescence, stable redox states, metal-ion coordination ability, aggregation or crystallization-induced phosphorescence or fluorescence emission (AIE or CIE). Some uses will be presented as asymmetric catalysts, as some of the most phosphorescent organic (nano)crystals (??~100%), as cation-selective membranes, as cations/anions sensors (dual mode), as electrochromic molecular switches, as multivalent glycosylated biosensors, and as ligands for stabilizing metal alloys and bimetallic core-shell nanoparticles.

    Abstract

    In this talk we will review some recent progress on the design and nanoengineering of inorganic and carbon nanomaterials for tailored applications. Special emphasis is paid in the group to exploit the synergies of both types of materials by the preparation of nanohybrids with novel or enhanced properties. We will mainly focus on the development of nanomaterials for application in the biomedical field, but we will also highlight work performed in other areas such as the isolation and template assisted-growth of rolled-up single-layered 2D materials. Among the different types of carbon nanomaterials, one advantage of using nanotubes is that their inner cavity can be filled with a chosen payload whilst the outer surface can be modified with biomolecules to improve their dispersibility, biocompatibility and even for targeting purposes. For instance, following this approach we have shown that by filling radioactive isotopes it is possible to achieve ultrasensitive imaging and the delivery of an unprecedented amount of radiodose density. The presence of selected heavy elements allows even mapping of subcellular organelles via X-ray fluorescence imaging. Furthermore, functionalization of the external walls of these filled carbon nanotubes (CNTs) with monoclonal antibodies allows targeting the epidermal growth factor receptor (EGFR), over expressed by several cancer cells. We have also recently developed CNTs for dual imaging by radio-labelling iron oxide decorating the external surface of CNTs. The resulting hybrids allow single photon emission computed tomography (SPECT) and magnetic resonance imaging (MRI). Worth noting is the enhancement of the MRI signal by modification of the nanocarrier (non-MRI active) rather than the magnetic nanoparticles themselves. The formation of such hybrid systems is not limited to the biomedical field. A large deal of attention is being devoted towards the isolation and growth of single layers of a wide variety of inorganic materials which is of interest for both fundamental research and advanced applications. When an individual layer is seamlessly wrapped into a cylinder, the resulting single-layered nanotube combines the characteristics of both two-dimensional (2D) and one-dimensional (1D) materials. Yet, despite their interest, reports on singlewalled inorganic nanotubes are scarce because their multiwalled counterparts are generally favored during growth. We have reported on a versatile approach that allows the formation of high quality, single-crystalline single-layered inorganic nanotubes.

  • Electron/hole transformation between two atomic layers

    Abstract

    Electron/hole transformations on interfaces determine fundamental properties of opto-electrochemical devices, but remain a grand challenge to experimentally investigate and theoretically describe. Herein combining ultrafast VIS/NIR/MIR frequencymixed micro-spectroscopy and state-of-the-art twodimensional atomic device fabrications, we are able to directly monitor the phase transitions of charged quasiparticles in real time on the ultimate interfaces – between two atomic layers. On type II semiconductor/ semiconductor interfaces between two transition metal dichalcogenide (TMDC) monolayers, interfacial charge transfers occur within 50fs and interlayer hot excitons (unbound interlayer e/h pairs) are the necessary intermediate of the process for both energy and momentum conservations. On semiconductor/ conductor (graphene) interfaces, interlayer charge transfers result in an unexpected transformation of conducting free carriers into insulating interlayer excitons between the conducting graphene and the semiconducting TMDC. The formation of interlayer excitons significantly improves the charge separation efficiency between the two atomic layers for more than twenty times.

He has published more than 100 peer-reviewed papers (h index 26) and coordinated several research programs. His research interests include the design of new metallating agents for functionalization of heterocycles, transition metal-catalyzed cross-couplings for ligand synthesis, and the design of photo- and electroactive organometallic materials.

    Abstract

    Functional heterocyclic derivatives are compounds of great importance with a wide spectrum of applications in e.g. biology, catalysis, supramolecular chemistry or energy conversion. The development of emerging technologies increases the need for more and more sophisticated heteroaromatic compounds drawing the synthetic chemist to design selective and applicable functionalization routes. Pyridine derivatives belong to one of the most important family and our group is focussing on chemo and regioselective routes to pyridyl organometallics (lithium [1] and ate complexes [2]). These intermediates are subsequently used in coupling reactions or enantioselective additions. The conference will focus on the preparation of a range of pyridyl organometallics from lab-made metalation reagents, their characterization and use for the synthesis of functional poly- and chiral heteroaromatic compounds.

    Abstract

    Herbal medicinal products have been playing an important role in the primary health care of the people around the world, specially in the developing countries. In order to treat health problems with the modern medicines, the production of safe and effective herbal medicinal products in a standardized way is essential. Assessment of the quality, safety and efficacy of herbal medicinal products are an important issue. Standardization of raw materials, intermediates and final product of herbal medicines are the main issue for the quality control of herbal medicinal products. All of the supporting evidence behind the use of phytomedicines has been on use of standardized extracts of the plant material to ensure reproducibility in the clinical setting. With the growing interest for alternative approaches in treating diseases, herbal medicinal products have also an important role for the development of new therapeutic agents. For this issue, researches should focus on: 1. characterization of phytomedicines in terms of chemical composition and biofunctional activity. 2. studying the effects of certain processing and extraction methods and parameters on the chemical characteristics of phytomedicines source materials. 3. development of chemo-based and bio-based standardization methods for phytomedicines. Herbal medicinal products named as “Phytomedicines” exhibit a variety of biological activities on human health. These range from the control of regulatory processes by Health Authorities is essential for human life. Therefore, herbal medicinal products are also subject to the same legislative controls as other medicines. The overview of the herbal medicinal products worldwide along with current registration guidelines and criteria for the control and market situation of herbal medicinal products in Turkey will be highlighted

    Abstract

    Protein aggregation of amyloids is associated with numerous incurable diseases, including amyloid ? (A?) in Alzheimer's disease (AD) and ?-synuclein in Parkinson's disease (PD). Clinical studies have shown that patients with AD can develop PD and visá- versa. Experimental evidence led to the hypothesis that cross-amyloid interactions (e.g., interactions between A? and ?-synuclein) also play a critical role in protein aggregation. Structure-based characterization of the interactions between two types of amyloids is fundamental to understanding the self-assembly mechanism that exists between them and may pave the way to elucidate the link between two diseases (e.g. PD and AD). Computational biophysical chemistry tools are critical techniques to investigate the molecular mechanisms of these proteins. The Nobel prize in Chemistry 2013 was awarded jointly to Martin Karplus, Michael Levitt and Arieh Warshel for the development of these techniques to investigate the chemistry behind the biological systems. The lecture will demonstrate how these computational tools assist us to investigate neurodegenerative diseases.

  • Substrate effects on silicene and how to exploit them

    King Abdullah University of Science and Technology
    Saudi Arabia
    Biography

    Udo Schwingenschlögl is a Professor of Materials Science & Engineering at King Abdullah University of Science and Technology.

    Abstract

    Silicene is the Si analogue of graphene with the same honeycomb structure and linear dispersions of the ? and ?* bands at the K point of the Brillouin zone. It is predicted to realize a buckled structure, due to sp2-sp3 hybridization, and is compatible with the current Si-based nano-electronics. Silicene yet has not been achieved by mechanical exfoliation but can be deposited on metallic substrates such as Ag(111), Ir(111), and ZrB2(0001). Regrettably, strong interaction to these substrates destroys the Dirac physics. For this reason, semiconducting substrates, including Si(111) and SiC(0001), have been explored theoretically to evaluate whether they lead to a Dirac cone with reasonable band gap (which is essential for applications). However, surface passivation is inevitable for these and similar substrates, due to their dangling bonds. Layered materials such as MgBr2(0001), MoX2, and GaX2 (X = S, Se, and Te), on the other hand, might preserve the characteristic electronic states of silicene and additionally simplify the preparation procedure as passivation is not required. The predicted effects of different substrates on silicene will be compared and evaluated with respect to technological requirements.
