Dendrimer characterization termination steps

In spite of the above difficulties, a reliable characterization of our dendrimers was achieved by using a variety of techniques. (1) Each compound (including precursors) was purified until TLC showed the presence of only one spot and checked to be stable under the experimental conditions. In particular no ligand scrambling was observed. (2) Each one of three types of steps (growth, deprotection, termination Figure 7) was accurately controlled as follows ...
