Abstract

Thermally labile dendronized AA-BB step polymers are described. First through third generation dendritic bisfuran monomers 6a-6c were prepared in part by the Cu(I)-catalyzed azide-alkyne Huisgen 1,3-dipolar cycloaddition reaction and in turn polymerized by the reversible furan-maleimide Diels-Alder reaction, The Diels-Alder reaction conditions were optimized through end-capping studies with N-phenylmaleimide (7). Dendronized step polymers 10a-10c were then formed from reaction with bismaleimide 9 and their assembly, disassembly, and reassembly behavior studied by GPC.
