ChemCon 2018

Acadia was once again very well represented at ChemCon, a regional undergraduate chemistry conference that was hosted by Saint Mary's University this year. Acadia students won the fifth most number of awards, behind Saint Mary's (9), Dalhousie (8), MUN (5) and UNB (5) students:

Scanning tunneling microscopy tip-assisted modification of Ti(IV) dithiothreitol self-assembled monolayers on Au(111): restructuring of the gold surface

M.L. Cappello, K.A. Hardy, A.R. MacDairmid, Mark C. Gallagher and Jeffrey T. Banks

Canadian Journal of Chemistry, 2013, 91, 364 (read paper)

Abstract:
Au(111) surfaces modified by exposure to a dilute solution of a Ti(IV)/dithiothreitol ligand to metal charge transfer complex (Ti(DTT)2) show a remarkable response to continuous scanning by scanning tunneling microscopy (STM). Vacancy islands on the gold surface, which are formed during the self-assembly of the molecular overlayer, coarsen and even merge during STM scanning at negative sample bias. In certain instances, the vacancy islands even line up to form parallel nanostructures. We believe the effect is due to mechanical interactions between tip and sample, which is enhanced by electrostatic effects. The Ti(DTT)2 complex is anchored to the gold surface via Au−S bonds, but due to the fact that there are multiple thiol groups, there may be “uncoordinated” thiols left “dangling”. The tip-induced modification involves the interaction of the tip with these “dangling” sulfurs, which in turn causes movement of single complex molecules with the attached sulfur-bonded gold. Under negative sample bias, the electric field weakens the binding between the sulfur-bonded gold atoms and the surrounding gold atoms in the surface allowing for the observed tip-induced dynamics. In contrast with the Ti(DTT)2 complex, a similar Ti(IV)/3-mercapto-1,2-propanediol complex (Ti(MPD)2) does not exhibit any tip-induced effects. In this case, there are no dangling sulfurs to interact with the STM tip. In addition, similarly prepared dithiothreitol, dithiothreitol titanium isopropoxide, and 3-mercapto-1,2-propanediol self-assembled monolayers (without dangling sulfurs) do not exhibit the tip-induced effect.

Opportunistic use of tetrachloroaurate photolysis in the generation ofreductive species for the production of gold nanostructures

Katherine L. McGilvray, Jenna Granger, Maria Correia, Jeffrey T. Banks and J. C. Scaiano

Physical Chemistry Chemical Physics,2011,13, 11914 (read paper)

Abstract:

The photolysis of gold salts is rarely viewed as the initiation for gold nanoparticle (AuNP) formation. Yet, photolysis of AuCl4 generates chlorine atoms whose rich hydrogen transfer chemistry can readily generate strongly reducing radicals. Interesting precursors include hydrogen peroxide, 2-propanol, 1,4-cyclohexadiene and tetrahydrofuran; all of them yield strongly reducing radicals. Further, this group of substrates has been selected because of the innocuous and volatile nature of reagents and products, thus allowing a remarkably clean synthesis of gold nanostructures. In the case of H2O2the by-products are water and oxygen. The methodology reported here opens the door to particles that can be modified in situ or post-synthesis with custom surface covering without concern for chemical debris from the nanostructure synthesis.

Diverse DNA-Cleaving Capacities of the Jadomycins through Precursor-Directed Biosynthesis

Krista M. Cottreau, Colin Spencer, Jason R. Wentzell, Cathy L. Graham, Charles N. Borissow, David L. Jakeman and Sherri A. McFarland

Organic Letters, 2010, 12(6), 1172 (read paper)

Abstract:

Gel mobility assays were used to establish that some members of the jadomycin family of natural products act as DNA cleaving agents. Moreover, it was found that subtle structural changes generated through the use of precursor-directed biosynthesis lead to marked effects on the DNA-damaging properties of these glycosylated polyketide-derived natural products.

Photobiological Activity of Ru(II) Dyads Based on (Pyren-1-yl)ethynyl Derivatives of 1,10-Phenanthroline

Susan Monro, John Scott, Abdellatif Chouai, Richard Lincoln, Ruifa Zong, Randolph P. Thummel and Sherri A. McFarland

Inorganic Chemistry, 2010, 49(6), 2889 (read paper)

Abstract:

Several mononuclear Ru(II) dyads possessing 1,10-phenanthroline-appended pyrenylethynylene ligands were synthesized, characterized, and evaluated for their potential in photobiological applications such as photodynamic therapy (PDT). These complexes interact with DNA via intercalation and photocleave DNA in vitro at submicromolar concentrations when irradiated with visible light (λirr ≥ 400 nm). Such properties are remarkably sensitive to the position of the ethynylpyrenyl substituent on the 1,10-phenanthroline ring, with 3-substitution showing the strongest binding under all conditions and causing the most deleterious DNA damage. Both dyads photocleave DNA under hypoxic conditions, and this photoactivity translates well to cytotoxicity and photocytotoxicity models using human leukemia cells, where the 5- and 3-substituted dyads show photocytotoxicity at 5−10 μM and 10−20 μM, respectively, with minimal, or essentially no, dark toxicity at these concentrations. This lack of dark cytotoxicity at concentrations where significant photoactivity is observed emphasizes that agents with strong intercalating units, previously thought to be too toxic for phototherapeutic applications, should not be excluded from the arsenal of potential photochemotherapeutic agents under investigation.

From PASS 1 to YES to AND logic: building parallel processing into molecular logic gates by sequential addition of receptors

David C. Magri and A. Prasanna de Silva

New Journal of Chemistry, 2010, 34, 476-481 (read paper)

Abstract:

The synthesis and photophysical characterization of a novel molecular logic gate 4, operating in water, is demonstrated based on the competition between fluorescence and photoinduced electron transfer (PET). It is constructed according to a ‘fluorophore–spacer–receptor1–spacer–receptor2’ format where anthracene is the fluorophore, receptor1 is a tertiary amine and receptor2 is a phenyliminodiacetate ligand. Using only protons and zinc cations as the chemical inputs and fluorescence as the output, 4 is demonstrated to be both a two-input AND and INH logic gate. When 4 is examined in context to the YES logic gates 1 and 2, and the two-input AND logic gate 3 and three-input AND logic gate 5, each with one or more of the following receptors including a tertiary amine, phenyliminodiacetate or benzo-15-crown-5 ether, logic gate 4 is the missing link in the homologous series. Collectively, the molecular logic gates 15 corroborate the PET ‘fluorophore–spacer–receptor’ model using chemical inputs and a light-signal output and provide insight into controlling the fluorescence quantum yield of future PET-based molecular logic gates.

Efficient Homogeneous Radical-Anion Chain Reactions Initiated by Dissociative Electron Transfer to 3,3,6,6-Tetraaryl-1,2-dioxanes

Donald L. B. Stringle, David C. Magri and Mark S. Workentin

Chemistry - A European Journal, 2010, 16(1), 178-188 (read paper)

Abstract:

A series of 3,3,6,6-tetraaryl-1,2-dioxanes (TADs) have been investigated at an inert electrode by using cyclic voltammetry, constant potential electrolysis and digital simulations. The series consists of the phenyl-substituted TAD (1 a), p-methoxy-aryl TADs (1 b, 1 c) and the p-methoxy/nitro-bearing TAD (1 d). The heterogeneous electron-transfer (ET) reduction is dissociative, causing rupture of the oxygen-oxygen bond, which generates a distonic radical-anion that reacts competitively either by β-scission fragmentation or ET. Fragmentation of the distonic radical anion yields an alkene, a substituted benzophenone, and a benzophenone radical anion. The benzophenone radical-anion propagates an efficient homogeneous ET-fragmentation chain reaction that accounts for the potential dependence of the product ratios and the low charge consumption observed in the controlled potential electrolysis experiments. Digital simulation of the experimental cyclic voltammograms allowed for estimates of the rate constants of the heterogeneous ET to the O—O bond, and for the rate constants for the β-scission fragmentation of the distonic radical-anions. Density functional theory calculations corroborate the differences in the heterogeneous kinetics of the initial dissociative ET. The endoperoxides 1 a-1 c react predominantly by a concerted dissociative ET mechanism, although the data suggests a stepwise dissociative pathway is also competitive. Bearing a nitro-aryl substituent, 1 d provides a rare example of an endoperoxide that proceeds by a stepwise dissociative ET mechanism. Irrespective of the initial mechanistic details, we find a propagating radical-anion cycle is a general mechanistic feature.
