The SCIENCE of NEW MATERIALS Our Identity and Missions Our identity and missions The internal organization of IPCMS (“Institut de Physique et Chimie des Matériaux de Strasbourg, UMR 7504 CNRS - Université de Strasbourg”) is based on five strongly interacting departments :Magnetics Objects on the Nanoscale (DMONS), Inorganic Materials Chemistry (DCMI), Organic Materials (DMO), Ultrafast optics and Nanophotonics (DON), Surfaces and Interfaces (DSI). The institute is an internationally well established research center in the area of nanomaterials and nanoscience. About 240 people work at IPCMS, among them ~ 80 are researchers and university professors/lecturers while 60 belong to the technical and administrative staff. Institut de Physique et Chimie IPCMS belongs to a regional network of laboratories active in material science, the “Alsace research federation in des Matériaux de Strasbourg materials and nanosciences”. Along the same lines, IPCMS plays an important role in several inter-laboratory Institut de Physique et Chimie networks active in France, such as the C’Nano (competences center in nanosciences), METSA (national UMR 7504 CNRS-UNISTRA electron microscopy network) and Synchrotron facilities. des Matériaux de Strasbourg 23 rue du Loess - BP 43 67034 STRASBOURG Cedex 2 National projects France Our departments : of investment for the future IPCMS Magnetic Objects on the Nanoscale Tel.: +33 3 88 10 71 41 IPCMS is a driving force promoting Equipex ARAGOInorganic Materials Chemistry (dedicated excellence equipments) and Labex A4 Fax : +33 3 88 10 72 50 (Paris - r. du (excellence network laboratories) initiatives.

  • A New Family of Optically Controlled Logic Gates Using Naphthopyran Molecule
    International Journal on Organic Electronics (IJOE) Vol.1, No.1, April 2012 A NEW FAMILY OF OPTICALLY CONTROLLED LOGIC GATES USING NAPHTHOPYRAN MOLECULE V.Mugundhan 1 1Department of Electronics and Instrumentation Engineering, SRM University, Kattankulathur, Tamil Nadu [email protected] ABSTRACT Microelectronics is predicted to reach its limit in another five to six years. As an alternative substitute, molecular electronics is analysed as an option, owing to its low power consumption and also very less area occupied by it(typically nm2). Conventional molecular electronic structures for molecular computational structures have been presented in the past. Naphthopyran in one potential candidate in creating optically controllable switches due to its bi-stability. It switches between the open ring and closed ring structures effectively when illuminated with light. In this paper, we will theoretically present a family of logic gates which are controlled optically, using Naphthopyran and associated architectures for basic structures such as AND, OR, XOR, Controlled NOT, Half adder and full adders, which are controlled optically. We see this as a step towards achieving the integration of molecular electronics and photonics, and thus, fabrication of IC like circuits employing the above. KEYWORDS Naphthopyran, Azobenzene, Self assembled Monolayers(SAM), Photo-isomerisation, Molecular electronic logic gates(MELG). 1. INTRODUCTION AND BACKGROUND STUDY Molecular electronics has been investigated as a potential candidate for achieving bottom up fabrication and low power electronics. The attractive feature of this type of materials is that they can self assemble on a substrate. As we go deeper into the subject of molecular electronics, we see a very wide difference from conventional inorganic materials based electronics that is being used in present day electronics.

This paper describes four significant breakthroughs in the syntheses and testing of molecular scale electronic devices. The 16-mer of oligo(2-dodecylphenylene ethynylene) was prepared on Merrifields resin using the iterative divergent/convergent approach which significantly streamlines the preparation of this molecular scale wire. The formation of self-assembled monolayers and multilayers on gold surfaces of rigid rod conjugated oligomers that have thiol, α, ω-dithiol, thioacetyl, or α, ω-dithioacetyl end groups have been studied. The direct observation of charge transport through molecules of benzene-1, 4-dithiol, which have been self-assembled onto two facing gold electrodes, has been achieved. Finally, we report initial studies into what effect varying the molecular alligator clip has on the molecule scale wire’s conductivity.

  • Plasmonic Tunnel Junctions for Single-Molecule Redox Chemistry

Baumberg 1 Nanoparticles attached just above a flat metallic surface can trap optical fields in 1234567890 the nanoscale gap. This enables local spectroscopy of a few molecules within each coupled plasmonic hotspot, with near thousand-fold enhancement of the incident fields. As a result of non-radiative relaxation pathways, the plasmons in such sub-nanometre cavities generate hot charge carriers, which can catalyse chemical reactions or induce redox processes in molecules located within the plasmonic hotspots. Here, surface-enhanced Raman spectroscopy allows us to track these hot-electron-induced chemical reduction processes in a series of different aromatic molecules. We demonstrate that by increasing the tunnelling barrier height and the dephasing strength, a transition from coherent to hopping electron transport occurs, enabling observation of redox processes in real time at the single-molecule level. 1 NanoPhotonics Centre, Cavendish Laboratory, Department of Physics, JJ Thompson Ave, University of Cambridge, Cambridge CB3 0HE, UK. 2 Melville Laboratory for Polymer Synthesis, Department of Chemistry, University of Cambridge, Lensfield Road, Cambridge CB2 1EW, UK. 3 Department of Materials Science and Engineering, Rensselaer Polytechnic Institute, Troy, 12180 NY, USA. 4 John A.
