Single Bond Control of Polycyclic Hydrocarbons
Abstract
Title: Single Bond Control of Polycyclic HydrocarbonsObjective: The scientific objective of the proposed research is to obtain chemical control of polycyclic hydrocarbons as the building blocks for graphene and as a gateway to fundamental chemical understanding by resolving, manipulating, spectroscopically characterizing, visualizing, and probing single bond selected chemistry.Approach:This project builds, characterizes, and images individual polycyclic hydrocarbons that increase in size towards the properties of nanoscale graphene and may exhibit unexpected novel chemical, optical, magnetic, and electrical behaviors that are distinct from macroscopicmaterials. The main tools to be utilized are high-resolution low-temperature STM and the new tool invented by the PI known as itProbe (inelastic tunneling probe).SOW:Specific tasks for this research project are as follows:1. Use and expand the capabilities of the STM to image,manipulate, spectroscopically characterize [particularly with the inelastic tunneling probe (itProbe)] the vibrational, electronic, and skeletal structure, and bonds in single molecules on metal and thin oxide surfaces.2. Image the formation of trichloroethylene trimers and induce the C-H bond dissociation and C-C bond formation to produce monocyclic benzene3. Elucidate the nature of the hydrogen bond in halogenated hydrocarbon4. Exploit the unique capabilities of the itProbe for structural determination of precursors and products5. itProbe imaging and carbon ring closure of Gorodetsky~s molecules6. Formation of bicyclic and tricyclic hydrocarbons7. Synthesis bilayer single crystal SiO2 and Al2O3 films on metal substrate8. itProbe of precursors on SiO2 and Al2O3 surfaces and selected chemistry to form polycyclic hydrocarbons on these surfaces9. Formation of polycyclic hydrocarbonsMerit and Relevance:This project is highly relevant to, and complementary to, several existing ONR initiatives (FY12 BRC, FY16 MURI etc.). In particular, PI s unique capability in terms of itProbe will be a key enabler of bottom-up synthesis of grapheme nanoelectronics.
