VALDES, Aristides C.; PINA-LUIS, Georgina  and  RIVERO, Ignacio A.. Parallel Synthesis of Polystyrene Anchored Imine Sulfide Materials: Sorption and Metal Sensing Studies. J. Mex. Chem. Soc [online]. 2007, vol.51, n.2, pp.87-95. ISSN 1870-249X.

In the present work we report the synthesis of a combinatorial library of 30 phenyl-ethyl based N-derivatives [nitro, amines and imines] bound to PS-thiophenol resin. The five step reaction sequence was characterized by ¹H NMR, MS and fluorescence spectroscopy of resin beads. The imines were screened for those that exhibited a large sorption capacity for Cu(II) and Pb(II) ions and those exhibiting a large fluorescence change upon the metal binding.

Keywords : Combinatorial library; solid phase; sensors; fluorescence.
