Abstract

Abstract. 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.

Resumen. Se reporta la síntesis de una biblioteca combinatorial de 30 N-derivados fenil etilo (nitro, aminas e iminas) unidos a una resina PS-tiofenol. La secuencia de 5 pasos de reacción fue seguida por 1H RMN, EM y espectroscopia de fluorescencia de la resina. Las iminas fueron monitoreadas para aquellas que mostraron gran capacidad de porción para iones Cu(II) y Pb(II) y aquellas que mostraron un gran cambio de fluorescencia por la unión al metal.
