In this laboratory exercise, a peroxyoxalate chemiluminescence experiment has been integrated with a combinatorial synthesis experiment. Students prepare a number of esters, in reactions between acyl chlorides and phenols, and test the compounds for chemiluminescence. If the experiment is parallel combinatorial synthesis, each student prepares one to two esters; if the experiment is mix-and-split combinatorial synthesis, each student prepares two mixtures of esters. Results from the entire class are combined, and based on the results, the students identify general structural features of an active (chemiluminescent) ester. In addition to rubrene, which emits the most intense light, a number of inexpensive fluorophores are suitable for this experiment including chlorophyll and anthracene. The laboratory exercise is suitable for introductory organic chemistry students and can be modified for more advanced students.

Dihydrodioxetobenzodioxins Synthesis and Chemiluminescence.
Lynmarie Thompson, chemistry and M2M, was awarded a two year, $615,000 NIH grant entitled, "Assembly and Function of Bacterial Chemotaxis Receptor Signaling Complexes.” The goal of this project is to assemble native-like functional nanoarrays of chemotaxis receptor complexes and determine how the proteins change their structure and dynamics during signaling. Understanding signaling in this system may be useful for the development of novel antibiotics targeting similar signaling systems that are widespread in bacteria.
“The twist in the story is that we thought that the distance between the lights in the string was the most important. It is important, but what is more important is the way that multiple strings and their lights are carefully arranged. It turns out that the processing solvent we used acts to arrange and regulate the architecture, so the azobenzene molecules attached to the polymer are arranged very neatly and compactly. It basically acts to ensure that there can be maximum packing density.” says Venkataraman. Details appear in the current issue of .

Free radicals, natural antioxidants, and their reaction mechanisms
Synthesis of the C8 BODIPY monomers, dimers, and trimers, a C8 polymer, and N8 aza-BODIPY monomer and dimer was carried out. Methyl and mesityl C8-substituted monomers, dimers, and trimers were used. Dimers, trimers, and polymer were formed chemically through the β–β (2/6) positions by oxidative coupling using FeCl3. A red shift of the absorbance and fluorescence is observed with addition of monomer units from monomer to polymer for C8 dyes. The aza-BODIPY dye shows red-shifted absorbance and fluorescence compared with the C8 analogue. Cyclic voltammetry shows one, two, and three one-electron waves on both reduction and oxidation for the monomer, dimer, and trimer, respectively, for the C8 BODIPYs. The separation for the reduction peaks for the C8 dimers is 0.12 V compared with 0.22 V for the oxidation, while the trimers show separations of 0.09 V between reduction peaks and 0.13 V for oxidation peaks. The larger separations between the second and third peaks, 0.25 V for the oxidation and 0.2 V for the reduction, are consistent with a larger energy to remove or add a third electron compared with the second one. The BODIPY polymer shows the presence of many sequential one-electron waves with a small separation. These results provide evidence for significant electronic interactions between different monomer units. The aza-BODIPY dye shows a reduction peak 0.8 V more positive compared to the C8 compound. Aza-BODIPY dimer shows the appearance of four waves in dichloromethane. The separation between two consecutive waves is around 0.12 V for reduction compared with 0.2 V for oxidation, which is comparable with the results for the C8 dyes. Electrogenerated chemiluminescence (ECL) of the different species was obtained, including weak ECL of the polymer.

Synthesis of noble metallic nanoparticles, in general, and silver nanoparticles (SNPs), in particular, currently are of special interest. In the present paper, an overview of the enhanced properties of SNPs and consequential applications of SNPs are discussed. Common synthesis methods and their comparison with the microemulsion technology, particularly advantages of SNPs formation with microemulsion technology, are discussed. A brief overview of the basics of microemulsion technology for nanoparticles formation is also presented. The complete topical review of microemulsion synthesis technique used to date for the generation of SNPs is discussed comprehensively. Control parameters have been explicated for influencing size, size uniformity, and stability aspects of the SNPs reported in the literature, allowing a tailored synthesis for specific application. Recent modifications made on the synthesis of SNPs to obtain monodisperse, high yield and stability are also discussed. Lastly, some future trends and perspectives in these research areas are outlined.
