Stacked Antiaromatic Porphyrins, Ryo Nozawa, Hiroko Tanaka, Won-Young Cha, Yongseok Hong, Ichiro Hisaki, Soji Shimizu, Ji-Young Shin, Tim Kowalczyk, Stephan Irle, Dongho Kim, Hiroshi Shinokubo 2019 Nagoya University

Stacked Antiaromatic Porphyrins, Ryo Nozawa, Hiroko Tanaka, Won-Young Cha, Yongseok Hong, Ichiro Hisaki, Soji Shimizu, Ji-Young Shin, Tim Kowalczyk, Stephan Irle, Dongho Kim, Hiroshi Shinokubo

Tim Kowalczyk

Aromaticity is a key concept in organic chemistry. Even though this concept has already been theoretically extrapolated to three dimensions, it usually still remains restricted to planar molecules in organic chemistry textbooks. Stacking of antiaromatic π-systems has been proposed to induce three-dimensional aromaticity as a result of strong frontier orbital interactions. However, experimental evidence to support this prediction still remains elusive so far. Here we report that close stacking of antiaromatic porphyrins diminishes their inherent antiaromaticity in the solid state as well as in solution. The antiaromatic stacking furthermore allows a delocalization of the π-electrons, which enhances the two-photon absorption ...


The Study Of Nanoparticle Titanium Dioxide-Based Hydrogel For Dye Adsorption And Photo-Degradation, Reem M. Alsharari 2019 Clark Atlanta University

The Study Of Nanoparticle Titanium Dioxide-Based Hydrogel For Dye Adsorption And Photo-Degradation, Reem M. Alsharari

Electronic Theses & Dissertations Collection for Atlanta University & Clark Atlanta University

The objective of this research was to study the adsorption and photodegradation of crystal violet (CV) dye by using poly(2-hydroxyethylmethacrylate) (PHEMA) hydrogel and nanocomposite TiO2-PHEMA hydrogel. Since the TiO2 nanoparticle has poor solubility, another goal of this study was to make a uniform TiO2 nanocomposite gel. These gels can be used in water treatment and can be easily photodegrade by exposure of sunlight which is similar to exposing to UV-vis. PHEMA was synthesized by free radical polymerization. The nanocomposite gels were characterized by FT-IR and XRD to confirm the presence of TiO2 nanoparticles and CV dye inside the PHEMA ...


Expanding The Toolbox With Site-Specific Methods Of Bioconjugation, Tiauna S. Howard 2019 Seton Hall University

Expanding The Toolbox With Site-Specific Methods Of Bioconjugation, Tiauna S. Howard

Seton Hall University Dissertations and Theses (ETDs)

Bioconjugation is an important tool for studying complex biological systems, with site-specificity being the major challenge. Reactions based on amino acid derived organocatalysts have been widely used in organic synthesis, particularly for the asymmetric synthesis of small molecules but this concept has not been vastly explored on biomolecules. To combat these limitations, two chemical strategies are developed to effectively attach synthetic molecules site specifically to proteins. First, a protein modification technique based on conjugation at a non-native functional handle, an aldehyde or ketone, is developed. This functional handle is chemically introduced onto the biomolecules before undergoing the organocatalyzed aldol reaction ...


Application Of The Picoloyl Substituent In Carbohydrate Chemistry, Michael Mannino, Alexei V. Demchenko 2019 University of Missouri-St. Louis

Application Of The Picoloyl Substituent In Carbohydrate Chemistry, Michael Mannino, Alexei V. Demchenko

Michael Mannino

Stereocontrol of glycosylation reactions is a constant struggle in the field of synthetic carbohydrate chemistry. The application of the picoloyl (Pico) substituent can offer a numerous stereocontrolling avenues. The most popular application is the Hydrogen-bond-mediated Aglycone Delivery (HAD) method that provides excellent selectivity in the glycosylation of a variety of sugar substrates. The HAD method relies on the formation of an intermolecular hydrogen bond between the nitrogen atom of the Pico substituent on the glycosyl donor with the hydroxyl group of the glycosyl acceptor. This interaction provides a facial preference for the nucleophilic attack and hence provides powerful stereocontrol for ...


Bridging The Molecular/Material Divide: An Investigation Into The Properties Of Polyesters, Terra Marie M. Jouaneh 2019 University of Rhode Island

Bridging The Molecular/Material Divide: An Investigation Into The Properties Of Polyesters, Terra Marie M. Jouaneh

Senior Honors Projects

By definition, polymers consist of large molecules composed of small, repeating units called monomers. These monomers give characteristic material properties to polymers, whether they be the melting point, the folding character, or the inherent stability. Many of the objects we encounter on a daily basis are composed of polymers. These polymers may be synthetic, such as the plastic in disposable bags, or natural, like glycogen in the liver. Recent developments in biotechnology have used synthetic polymers in drug delivery, contact lenses, and even organ transplants. Polyesters, in particular, have been utilized pharmacologically due to their biodegradable properties. Understandably, not all ...
