Intramolecular crosslinking of benzylether-based dendrimers functionalized with electroactive carbazole peripheral groups is performed using both chemical and electrochemical methods. The changes in structure, rigidity, size, and conformation of the uncrosslinked and crosslinked precursor dendrimer nanoparticles are compared and modeled (see figure).
