Abstract: Horseradish peroxidase has been demonstrated to catalyze the oxidative polymerization of aniline to form conductive polyaniline. This process is facilitated by the presence of a macromolecular template with sulfonic acid groups that provide a unique environment for the formation of the conducting polymer. Here we report the use of a photo-cross-linkable thymine-based polymer with phenylsulfonate groups as a templating substrate. This allows for an aqueous-based environmentally benign photopatterning of a conductive material. A description and results of this process are presented.

Abstract: The synthesis and unequivocal characterization of all six isomers of benzoyl phenyl 1-methylpyrazole (2) are described. The isomer of 2 isolated as one of the products of the reaction of 1,1-dimethyl-1-phenacylhydrazinium bromide (1) with base was shown to be the only previously reported isomer, 5-benzoyl-3-phenyl-1-methylpyrazole (2b).

Abstract: Over the past 10 years, the science of green chemistry has continued to evolve and has been adopted in research labs in industry and academia. At the same time, new innovations in chemicals policy have widened opportunities for legislative action to protect human health and the environment. This article addresses the mechanisms by which the science of green chemistry and chemicals policy can work together to help attain a more sustainable future. It also speaks to the pitfalls of inappropriately merging these two, and explores how such a merger could inhibit the creation of sustainable technologies. Green chemistry's role in educational reform is discussed as a means for training students who are prepared to create truly sustainable technologies.

Abstract: Coatings of quaternary ammonium tertiary structures (QUATS) copolymerized with 4-vinylbenzylthymine (VBT) exhibited high antimicrobial activity against Escherichia coli. Immobilization of QUATS improves environmental performance by preventing release of antibacterials to the environment, helping to preclude the emergence of resistant strains. The crosslinking immobilization scheme reported herein provides a more environmentally benign and more inexpensive synthesis than previously reported, thus reducing the use of solvents, energy, and production time. Development of water soluble, thymine-based photopolymers was inspired by the UV-induced 2pi + 2pi photocyclodimerization of thymine in DNA. Copolymers of 4-vinylbenzylthymine and trimethylammonium chloride, triethylammonium chloride, or dimethyloctylammonium chloride were synthesized in different monomer ratios. The antibacterial properties were tested by coating VBT:QUATS in sterilized petri dishes, crosslinking under short UV light, spraying with aqueous suspensions of bacterial cells, air drying, and then applying agar media to promote bacterial growth. The plates were incubated for 24 h at 37 degrees C. The number of viable cells ranged from 17 to 0% growth. Immobilized VBT:QUAT copolymers are antiseptic surfaces that can be produced in an environmentally benign fashion.

Abstract: The increasing demand for crosslinked polymer microparticles (PMPs) in advanced applications requires the development of new sustainable methods which can reduce the impact of the polymerization process on the environment. This research reports a new environmentally‐friendly light‐assisted polymerization method for the synthesis of highly cross‐linked polymer microspheres by combining light‐induced [2+2] cycloadditions with dispersion polymerization. Using naturally‐occurring coumarin as reactive moieties, this method allows the synthesis of highly crosslinked PMPs in the presence of UV light at room temperature without initiator. The effect of the reaction parameters such as monomer concentration, stabilizer and reaction time on the particle size and yield are investigated using a number of techniques including Fourier transform infrared spectroscopy, solid‐state 13 C nuclear magnetic resonance spectroscopy, and scanning electron microscopy. The results show the formation of highly crosslinked porous microspheres which demonstrate good thermal stability.

Abstract: The traditional construction of materials is usually driven by classical synthetic transformations involving the making and breaking of covalent bonds. These processes often require high-energy input and highly reactive and hazardous materials. In natural systems, one typically encounters synthetic control schemes that are based on entropic forces rather than these human-designed enthalpic manipulations. In natural processes, phase changes and triggered mixing are often employed to direct systems toward or away from equilibrium conditions. The recognition of these "natural tendencies" allows one to design processes that have reduced toxicological and environmental impact. Results in noncovalent derivatization (NCD) and bioinspired photopolymers that illustrate this shift toward entropic control are described.

Abstract: Here, we report a sensitization study on a family of water-soluble photopolymers based on thymine. The goal of this study was to determine whether the presence of sensitizer molecules would promote photocrosslinking/immobilization of the polymers using low-energy irradiation (520 nm) as compared to the UV irradiation (approximately 280 nm) necessary for the standard photoinduced process to take place. With the aid of Eosin Y Spirit Soluble (EY) as a sensitizer, water-soluble polystyrene copolymers of vinylbenzylthymine-vinylbenzyltriethylammonium chloride (VBT-VBA) were immobilized after exposure to visible irradiation. By exciting the sensitizer molecule in the presence of VBT copolymers at a wavelength where absorption by the latter does not occur, the triplet state of the sensitizer is generated in high yields, and consequently, polymer photocross-linking takes place. UV-vis spectroscopy has been used to study the effect of irradiation dose, copolymer composition, and sensitizer concentration on the photoreactivity of VBT polymers. These studies demonstrate the feasibility of using Eosin Y as a sensitizer to achieve the thymine photodimer formation, resulting in immobilization of VBT-VBA-EY films on PET substrate. This provides complementary information on photoinduced immobilization of VBT-VBA films that are crucial for developing new classes of environmentally benign materials and new energy-saving methods.

Abstract: Dispersions of titanium dioxide nanoparticles with terephthalic acid, isophthalic acid, salicylic acid, benzoic acid, and pyridine-2,5-dicarboxylic acid were prepared by aqueous grinding. The pH of the dispersions was adjusted by adding either HCl or NaOH, and the viscosity of the dispersions was measured. It was found that the viscosity of the system depends strongly on pH. The qualitative interpretation of the results based on the DLVO theory is presented. The evidence of the effect of bridging interactions on the viscosity of titanium dioxide-dicarboxylic acid dispersions is discussed.

Abstract: A novel bioinspired molecule, 1,3-bis(vinylbenzyl)thymine (bisVBT), was isolated as a by-product during the synthesis of 1-(4-vinylbenzyl)thymine (VBT) and analyzed with various techniques: NMR, IR, and Single-Crystal X-ray Diffraction. In addition to embodying all the desired characteristics of VBT (i.e., having the ability to undergo a 2 π + 2 π photodimerization reaction upon UV irradiation, a derivatization site, hydrogen bonding sites, and aromatic stacking ability) the bisVBT monomer has the added benefit of having two vinyl groups for cross-polymerization. Copolymerizing the bisVBT monomer with the charged monomer vinylbenzyl triethylammonium (VBA) chloride, different copolymers/terpolymers/cross-linked network were obtained, as it was shown by the absence of the vinyl resonance in the NMR spectra. Thermal Gravimetric Analysis (TGA) and Differential Scanning Calorimetry (DSC) showed an indication of materials with low degree of cross-linking. A Gel Permeation Chromatography (GPC) method was improved to better characterize the molecular weight distributions of the cationic structures. Preliminary qualitative cross-linking studies were performed on bisVBT-VBA copolymers, and a comparison with VBT-VBA copolymers is presented.
