Embedment of Ag(I)-organic frameworks into silica gels for microextraction of polybrominated diphenyl ethers in soils.

J. Chromatogr. A. 1383 , 18-24, (2015)

Three Ag(I)-organic frameworks, [Ag5(pydc)2(CN)]n, {[Ag4(pydc)2]CH3CN}n, and [Ag(4,4'-bpy)NO3]n, were synthesized and embedded into silica gels to form metal-organic-framework (MOF)-embedded gels for ...

Direct identification of on-bead peptides using surface-enhanced Raman spectroscopic barcoding system for high-throughput bioanalysis.

Sci. Rep. 5 , 10144, (2015)

Recently, preparation and screening of compound libraries remain one of the most challenging tasks in drug discovery, biomarker detection, and biomolecular profiling processes. So far, several distinc...

Synthesis, resolution, and absolute configuration of chiral 4,4'-bipyridines.

J. Org. Chem. 77(6) , 2579-83, (2012)

A chiral polyhalogenated 4,4'-bipyridine derivative is described allowing an easy access to a new family of chiral 4,4'-bipyridines by site-selective cross-coupling reactions. The absolute configurati...
