Mallouk Professor of Chemistry, Biochemistry and Molecular Biology, Physics, and Engineering Science and Mechanics Head of the Department of Chemistry *Signatures are on file in the Graduate School iii ABSTRACT Carbon nanomaterials such as fullerenes, nanotubes, and graphene have been widely studied in recent decades. Benefitting from their unique bonding, they possess extraordinary physical and chemical properties. Compared with sp2 hybridized carbon allotropes, there are significantly fewer new carbon materials dominated by sp3 bonding that have been developed. Adamantane and graphane represent the smallest unit and thinnest sheet of diamond possible, respectively. One-dimensional, mostly sp3 hybridized nanocarbon, did not yet exist in 2013, when the first synthesis of carbon nanothreads finally filled up the last remaining entry in the matrix of dimensionality and hybridization of carbon nanomaterials that year. Carbon nanothread was first made by compressing benzene to ~25 GPa in a large-volume anvil cell and slowly decompressing back to ambient pressure by an alumnus of the Badding group.

This work is licensed under the Creative Commons Attribution International License (CC BY). http://creativecommons.org/licenses/by/4.0/ Abstract In the course of time, numerous rules were proposed to predict how atoms connect through cova- lent bonds. Based on the classification of elements in the periodic table, the rule of eight was first proposed to draw formulas of organic compounds. The later named octet rule exhibited short- comings when applied to inorganic compounds. Another rule, the rule of two, using covalent bonds between atoms, was proposed as an attempt to unify description of organic and inorganic mole- cules. This rule unfortunately never managed to expand the field of application of the octet rule to inorganic compounds. In order to conciliate organic and inorganic compounds, the recently put forward even-odd and the isoelectronicity rules suggest the creation of one group of compounds with pairs of electrons. These rules compass the rule of two for covalent bonds as well as the octet rule for organic compounds and suggest transforming bonds of multi-bonded compounds in order to unify representations of both groups of compounds.

    15th European Workshop on Phosphorus Chemistry EWPC 15/2018 March 14-16, 2018 Uppsala University, Uppsala, SWEDEN European Workshop on Phosphorus Chemistry - EWPC 15/2018 March 14-16 Dear Participants of the EWPC-15, The long tradition of workshops previously held in Kaiserslautern (2004), Bonn (2005), Leipzig (2006), Zandvoort (2007), Regensburg (2008), Florence (2009), Budapest (2010), Münster (2011), Rennes (2012), Regensburg (2013), Sofia (2014), Kassel (2015), Berlin (2016), and Cluj-Napoca (2017) will be continued with the 15th European Workshop in Phosphorus Chemistry in Uppsala, Sweden. This traditional workshop series has contributed to the strong position of the European research community and allowed for a fruitful exchange of ideas, opinions and excellent discussions. The topics of this conference cover organic, inorganic, polymer, and material chemistry as well as biological research. The program comprises 30 oral presentations from experienced researchers and PhD students, and a round table discussion on the future of phosphorous chemistry. The first evening will be concluded by a “Rektorsmottagning”, a Principals reception, at the University Main Building, which was inaugurated in 1887. The second day full of scientific program ends with a convivial conference dinner at the Restaurant Sven Dufva, located at the Science Park Uppsala. The last day of science will end with the traditional awards for the Best Posters, Best Chair and Best Presentations. Our aim is to create a vivid atmosphere that fuels discussions in this multidisciplinary field of research. We are aiming to re-inforce the (European) network of researchers by this annual conference. A specific goal of this conference series is, to provide young researchers a platform to present and discuss their science with peers and experienced researchers, alike.

    European Workshop on Phosphorus Chemistry - EWPC 15/2018 March 14-16 ORAL PRESENTATIONS Uppsala University, SWEDEN European Workshop on Phosphorus Chemistry - EWPC 15/2018 March 14-16 Bridged Triarylphosphines as Versatile Platforms for the Construction of Polycyclic Heteroaromatic Compounds Milan Kivala,a,* Johannes Ascherl,a Tobias A. Schauba,b and Frank Hampela aDepartment of Chemistry and Pharmacy, University of Erlangen-Nürnberg. Erlangen. Germany. bDepartment of Chemistry and Biochemistry, University of Oregon. Eugene. Oregon. USA. [email protected] The incorporation of heteroatoms directly into the sp2-carbon skeleton of polycyclic aromatic hydrocarbons (PAHs) provides a powerful tool – next to variation of their size and periphery and/or lateral decoration with various substituents – to manipulate their optoelectronic properties and supramolecular behavior.1,2 This is particularly relevant in the context of organic electronics for which -conjugated organic materials finely tuned in terms of their photophysical, redox, and self-assembly properties are of high demand. Rather surprisingly, the field of phosphorus-containing PAHs is still in its infancy, although such compounds often show strikingly different properties from their nitrogen- containing counterparts such as the unique pyramidal geometry and the Lewis basicity of the phosphorus centre, providing for additional chemistry.3 We have recently identified various relatively simple bridged triarylphosphine derivatives as versatile building blocks for the construction of unprecedented phosphorus-containing PAHs.4 This contribution will address our respective synthetic efforts and the fundamental characteristics of the resulting compounds.

    Tutopiya’s GCE O Level Chemistry Mid-Year Examination Notes Made by: Tutopiya Atomic Structure (Source) Isoelectronic: Isoelectronicity happens when two or more molecules have the same structure and the same electron configurations. However, they differ by what specific elements are at certain locations in the structure. Isotopes: Isotopes are two or more types of atoms that have the same atomic number and position in the periodic table. They differ in nucleon numbers due to different numbers of neutrons in their nuclei. Finding the relative atomic mass of isotopes • Add an abundance of the first isotope multiplied by its atomic mass to an abundance of the second isotope multiplied by its atomic mass and so on and so forth and then divide it by the number of isotopes. • The formula is as follows: (Source) Electronic structure - s,p,d,f,g orbital notation Aufbau Principle - Electrons fill up orbitals of lowest energy first before proceeding to higher energy levels Pauli exclusion principle An orbital can only hold a max of 2 electrons of opposite spins Hund’s rule of multiplicity Electrons occupy different orbitals each first before pairing up in each orbital 1s,2s,2p,3s,3p,3s,4s,3d…… Overlap in energies of certain layers: 4s and 3d, 3d is higher In the case of ions drawing electrons will draw from 4s first before 3d even if it’s a higher orbital s = 2, p =6, d=10, f= 14 Can write using noble gas core 1s2,2s2,2p6,3s2 as [Ne] 3s2 Separation Techniques Filtration - A separate mixture of insoluble solid and liquid - Mixture poured through

Chem. Chem. Phys., 2015, 17,27281 phosphine ices† Andrew M. Turner,a Matthew J. Abplanalp,a Si Y. Chen,b Yu T. Chen,b Agnes H. H. Chang*b and Ralf I. Kaiser*a Isovalency rationalizes fundamental chemical properties of elements in the same group, but often fails to account for differences in the molecular structure due to the distinct atomic sizes and electron-pair repulsion of the isovalent atoms. With respect to main group V, saturated hydrides of nitrogen are limited to ammonia (NH3) and hydrazine (N2H4) along with ionic and/or metal-bound triazene (N3H5) and potentially tetrazene (N4H6). Here, we present a novel approach for synthesizing and detecting phosphanes formed via non-classical synthesis exploiting irradiation of phosphine ices with energetic electrons, subliming the newly formed phosphanes via fractionated sublimation, and detecting these species via reflectron time-of-flight mass spectrometry (ReTOF) coupled with vacuum ultraviolet (VUV) single photon ionization. This approach is able to synthesize, to separate, and to detect phosphanes as Received 16th May 2015, large as octaphosphane (P8H10), which far out-performs the traditional analytical tools of infrared Accepted 21st July 2015 spectroscopy and residual gas analysis via mass spectrometry coupled with electron impact ionization DOI: 10.1039/c5cp02835c that could barely detect triphosphane (P3H5) thus providing an unconventional tool to prepare complex inorganic compounds such as a homologues series of phosphanes, which are difficult to synthesize via www.rsc.org/pccp classical synthetic methods.
