Supramolecular dendrimers: Convenient synthesis by programmed self-assembly and tunable thermoresponsivity

Research output: Contribution to journalArticle

Abstract

We report here the noncovalent synthesis of thermosensitive dendrimers. Short oligoguanosine strands were linked to the focal point of a dendron by using "click chemistry", and quadruplex formation was used to drive the self-assembly process in the presence of metal ions. The dynamic nature of these noncovalent assemblies can be exploited to create combinatorial libraries of dendrimers as demonstrated by the co-assembly of two components. These supramolecular dendrimers showed thermoresponsive behavior that can be tuned by varying the templating cations or the number of guanines in the oligonucleotide strand.
