Kurzfassung englisch:
Studies on the applicability of conventional liquid-state NMR spectroscopy for the analysis of solid-phase organic reactions directly on the resin will be described. For a systematic investigation small and easily assignable molecules substituted with a chain of varying length were synthesized. In a subsequent step these so-called sensor molecules were attached to commercially available resins. After swelling experiments, 13C NMR spectra of the solid phase systems in gel form were recorded using Composite Pulse
Decoupling (CPD) and Attached Proton Test (APT) techniques. The quality of the resulting spectra was analyzed using the half-height linewidths of the signals as the most important criterion. Based on these data, the parameters to obtain high quality spectra were determined.
