","Synthesis and Characterization of Trimetallic Cu(I), Au(I) and Ag(I) Complexes","Abstract: The design and preparation of multinuclear metal complexes or coordination polymers containing direct metal-metal interactions, such as Pt-Ag, Pt-Tl, Pt-Pt, Pt-Pd, Au-Au, Ag-Ag, and Cu-Cu has received considerable attention. Among them, emissive copper(I) complexes are expected to be key materials for preparation of organic light emitting diodes likely because copper(I) is more cost-effective than the other precious metal complexes. In these systems metallophilicity plays an important role in assembling close M···M interactions. Earlier our group reported the application of the 2-picolyl substituted NHC ligand toward stabilizing Ag(I)-Ag(I) interactions. The simple reaction of the NHC ligand precursor 1,3-bis(2-pyridinylmethyl)-1H-imidazolium tetrafluoroborate, [H(pyCH2)2im]BF4 with silver oxide in acetonitrile produces the unusual triangulo-Ag3 cluster, [Ag3((pyCH2)2im)3](BF4)3, with unusually short Ag-Ag separations (2.72 to 2.78 Å). We have now extended this chemistry to explore the electronic alteration of the ligand on the metal-metal separation. Additionally, we were able to produce mixed metal systems, and copper triangulo-Cu3 clusters. ","submitted","1.

These macrocycles can be accessed in one-pot base catalyzed reactions of 2,3-dichloronaphthoquinone and various diphenols. Modifications to the electrophile and reactions conditions were also explored to access similar structures. Subsequently, each macrocycle was investigated for its ability to act as a supramolecular host for host-guest binding. ","submitted","1.

","Vibrational spectroscopy of asparagine in acidic, neutral, and basic solutions","Abstract: Fourier transform infrared spectroscopy (FTIR) utilizing attenuated total reflectance (ATR) was carried out to analyze changes in vibrational bands of asparagine (L-Asn) at 0.20 M concentration in acidic, neutral, and basic solutions in the pH range of 1 to 14. The spectra show evolution of peaks near 1730, 1680, 1260, and 1228 cm-1 at pH values below 2, suggesting protonation of the carboxylic acid on the backbone of the molecule. The appearance of peaks near 1530, 1400, and 1360 cm-1 at pH values in the 2 - 8 range implies that the amino acid adopts a zwitterionic structure. ","submitted","1.

","Structural study of Mongolian tourmaline in the electric power saving system with infrared spectroscopy","Abstract: This Fourier Transformation Infrared (FTIR) experiment investigates the relevance of H2O and other components’ structural environments. Four element materials, tourmaline, ferrite, NaCl, and H2O, comprised the electronic power saving system. FTIR spectroscopy in the range of 3,000 to 4,000 cm-1 was used to examine the hydroxyl ions of H2O and Mongolian tourmaline. The tourmaline crystal was polar and therefore pyroelectric, electrical charges developing at the ends of the polar axis and temperature changing from the IR activation with H2O in the system. As a result, the tourmaline was shown to be related to the activation of H2O as a pyroelectric substance. ","resubmitted","1.

","Calculation of the anharmonic effect of elementary reactions of high-temperature combustion reaction","Abstract: Abstract Combustion plays an important role in engineering and our life. Today, about 90 percent of the energy is generated by the combustion in our world [1]. Focusing on the chemistry of combustion of fuels, it is of great significance to design the combustion chamber, control pollutants and research on alternative fuels [3-4]. The chemical kinetic mechanism of combustion of fuels is composed of a series of elementary reactions. Therefore, to better grasp the mechanism of combustion reaction, it is necessary to investigate the elementary reaction process. Being the key parameters of the chemical kinetic mechanism of the combustion reactions, the rate constant are calculated using RRKM theory, transition state theory and our own method. Most results are similar with those of accurate quantum dynamics (QD). At the same time, the RRKM theory, the intramolecular vibration theory, and the vibrational transition state theory for large molecule reaction systems, or the gas-phase reaction kinetics that are difficult to investigate by using accurate quantum dynamics and quasi classical trajectory method provide the feasibility of estimating. We investigate the anharmonic effect of the canonical and the microcanonical systems, and calculate the total number of states, the density of the states, the partition function and the rate constant. From the various calculation results, we get the following conclusions. First, the anharmonic effect is significant for the weak binding force of microscopic reaction systems. Second, the error of harmonic approximation is larger in high temperature, which is announced for the kinetic mechanism of the combustion reactions. Third, when the molecular reaction is 2000 K, the anharmonic rate constant is smaller than the harmonic rate constant ranging from 2 times to thousands times. The anharmonic effect increase with the increasing temperatures. Forth, the anharmonic effect is not only related to the intramolecular bond length and binding energy, but also with the symmetry of the molecular structure. We will focus on the developing the anharmonic model of high-temperature combustion reactions in the following days, high-temperature non-resonant correction calculation methods and apply the method and parameters to building and optimizing the kinetic mechanism of the high-temperature combustion of hydrocarbons.

","Modified Sonogashira- and Glaser-type couplings: Reaction methodology for undergraduate research","Abstract: Due to their structural rigidity, conjugation and unique bond torsion, sequence-specific arylethynylene and arylbutadiyne oligomers are excellent scaffolds for the study of shape-persistent supramolecular and nanoscale systems. With the ultimate goal of improving the generation of these important architectures, new synthetic methodologies have been developed utilizing an in situ ethynylsilane deprotection reaction. While synthetic strategies for the alkynylation of aryl moieties (Sonogashira) or the homocoupling of alkynes (Glaser) traditionally involve iterative pathways, the use of an in situ ethynylsilane deprotection reaction has been shown to allow for the rapid construction, often in one pot, of complex arylethynylene and arylbutadiyne oligomers. Key to the protocol is the inclusion of a mixture of amidine base, such as 1,8-diazabicyclo[5.4.0]undec-7-ene (DBU), CuI and substoichiometric amounts of water. The use of trimethylsilylacetylene versus bis-trimethylsilylacetylene, base toggling, inclusion of dioxygen for homocoupling, sterics of silylacetylene protection and CO insertion projects will be discussed.

","Design and synthesis of nitrogen rich porous organic polymers","Abstract: Recently porous organic polymers have been widely studied because of their multifunctionalilty. They have potential uses in areas such as storage, separation, and catalysis. It has been found that nitrogen rich porous organic polymers play significant roles in gas storage capacity and selectivity. We report here the synthesis of benzimidazole–linked polymers. Synthesized polymers are chemically and thermally stable due to the stability of benzimidazole moiety. Suitable building unit have been selected and synthesized to enrich the overall nitrogen heterogeneity in the frames. The polymers have moderate surface areas of around 500 m2g-1. Details synthesis and porous studies will be reported in poster presentation. ","submitted","1. Chemistry, University of Wisconsin-Platteville, Platteville, WI, United States.  2.
