, p. 1461 - 1470 (2009)
The anionic fluorescent dye, aminopyrene trisulfonic acid (APTS), was synthesized and used in a solution-based two-component glucose-sensing system comprising the dye and a boronic acid-appended viologen. The fluorescence of the dye was quenched in the pr

, p. 4160 - 4162 (2010)
A fullerene hexakis-adduct incorporating complementary reactive centres with very different and selective reactivity has been prepared and functionalized with three different peripheral groups by successive alkyne-azide and thiol-ene click reactions.

Terminal hydroxylated acrylates and methacrylates were prepared by catalytic transesterification of acrylates and methacrylates with diols catalyzed by a system of a tetranuclear zinc alkoxide, [Zn(tmhd)(OMe)(MeOH)]4 (1a), with 4 equiv. of 2,2′-bipyridine (L1). The reaction time to reach the equilibrium state was analyzed by kinetic studies and a curve-fitting analysis based on the Runge-Kutta method for optimizing the best reaction conditions for mono-esterification. In addition to these kinetic analyses, DFT calculations estimated a proposed mechanism of the catalytic transesterification. This journal is
