New Strategies

AbstractThe electrochemical properties of o-dianisidine have been studied in both aqueous and organic solvents. This aryl diamine has been electrochemically polymerized on ITO coated glass electrodes and it was determined that the optical properties of these films are influenced by the polymerization conditions. The use of this polymer film as substrate for chemical coupling of biomaterials has been demonstrated with the light harvesting protein, phycoerythrin. Fabrication and bioanalytical application of enzyme electrodes by electrochemical copolymerization of odianisidine with the enzymes glucose oxidase and horseradish peroxidase, modified with odianisidineis described.

AbstractBenzyl 9H-carbazole-9-carbodithioate (BCC) was synthesized and characterized. The single-crystal structure of BCC was first reported. The RAFT polymerizations of styrene and acrylates using BCC as the RAFT agent under conventional polymerization conditions were investigated. The results showed that the BCC was an effective RAFT agent for the polymerizations of styrene and acrylates. The well-controlled polymers were labelled with carbazole group, which was confirmed by 1H NMR and the chain extension of the obtained polymer. Azo modified poly(methyl acrylate) (PMA) was synthesized through a postpolymerization azo-coupling scheme. The optical properties of obtained polymer were also characterized. The results showed that the carbazole group labelled polymer exhibited fluorescence and the azo polymer exhibited UV absorption behaviour in N,N-dimethyl formamide (DMF).

Thieno[3,2-b]pyrrole is an effective nonconventional semiconducting building block that could be generated in gram quantities with relatively high overall yields. Three organic semiconductors containing thieno[3,2-b]pyrrole were synthesized in good yields without requiring time-consuming column purifications. The synthesis, optical and electrochemical properties were systematically investigated.1 Introduction2 Experimental3 Synthesis and Characterization4 Theoretical Calculations5 Optical and Electrochemical Properties6 Thermal Stability7 Fluorescence Experiments8 GIXRD Data9 Conclusions

AbstractAn approach to prepare metal nanoparticle-polymer microbeads with integrated Raman tags using SERS as reliable diagnostic tool is reported. In essence, spectroscopically encoded (4-thioacetyl)styrenes were assembled on well-characterized 50 nm Au NPs and subjected to suspension polymerization conditions using styrene and methacrylic acid as comonomers and divinylbenzene as crosslinker. The resulting metal embedded nanocomposites were characterized by SEM, TEM, DSC, TGA, Raman and SERS to determine their morphology, particle size, composition, thermal stability and their optical and electronic properties.
