Functionalization of polymers and carbon nanomaterials with low molecular weight receptors

Michał Cegłowski

Abstract

Controlled chemical functionalization of materials achieved by introduction of defined functional groups to their structure, permits endowing the materials with specific target properties. The aim of my doctoral dissertation was to design a method for the synthesis and to synthesise new functionalized carbon materials and polymers, containing molecular receptors capable of selective binding ions or molecules and showing defined properties. One of my tasks was to obtain new matrices to be employed for matrix-assisted laser desorption/ionization mass spectrometry (MALDI-MS), which would not generate signals in the mass spectra in the region of low molecular mass. I functionalized carbon nanotubes surface with sinapic. The materials obtained were applied as matrices in the MALDI-MS analyses of surfactants, folic acid and vancomycin. In order to functionalize certain polymers, it was necessary to obtain receptors that would be selective towards a given analyte and reactive towards the functional groups present in the polymer structure. The first task was to obtain materials capable of selective interactions with sugars and diols. The second aim of polymer functionalization was to obtain materials capable of adsorption of transition metal cations.
