A library of G1-G3 alpha-amino acidbased layer-block dendrons 1-6 containing different aminoacid residues in the different concentric layers was prepared by solution-phase peptide synthesis. The structures of these dendrons were characterized by 1H and 13C NMR spectroscopy and, except for the G3 series of compounds, by mass spectrometry. The purities of these compounds were also determined by size-exclusion
