Polymelamine dendron

In another study,two approaches for synthesis of the polymelamine dendrons on silica gel were experimentally compared the divergent solid-phase synthesis (Scheme 15.26b)... 

Scheme 15.25. Synthesis of polymelamine dendrons on solid support by Marsh et al.

Removal of another pollutant, atrazine herbicide, by polymelamine dendrons on silica was demonstrated by Simanek and coworkers. The authors revealed two trends. First, the dendrons of higher generation increased the sequestering ability of the hybrid material relative to that of the support modified with the lower generation dendrons. Second, this ability was higher for the dendrons divergently grown on silica, compared to the materials obtained by the focal-point immobilization of the dendrons presynthesized in solution (see Section 15.2.9). 

Su and coworkers used silica gel with immobilized polymelamine, poly(amidoamine), or poly(propylenimine) dendrons as the microcolumn packing for the flow injection preconcentration and separation of traces of Pt(IV) ions for flame atomic absorption spectroscopy determination.Polyamine dendron-functionalized polystyrene was...
