Reversible self-assembly of dendrimer based on polyhedral oligomeric silsesquioxanes (POSS)

An acid-base switchable dendritic complex was constructed by self-assembly between dibenzo-24-crown-8 terminated T-10-POSS dendrimer and dibenzylammonium hexafluorophosphate salt based on T-8-POSS. The formation and its threading-dethreading property were characterized by H-1 NMR and UV-visible absorption spectroscopy.
