Dendrimers Based on Thermally Reversible Furan−Maleimide Diels−Alder Adducts

Abstract

Thermally labile dendrimers based on the reversible furan−maleimide Diels−Alder reaction are described. First through fourth generation benzyl aryl ether based dendrons 3a − d that contained furan moieties at their focal point were allowed to react with bismaleimide central linker 4 to provide the corresponding dendrimers 5 − 8 . Thermal degradation and reassembly of these dendrimers were studied under a variety of conditions and monitored by GPC and NMR.
