A new class of globular polybranched macromolecules that contain multiple anionic metallacarborane clusters at the o ‐carborane periphery is reported. The water soluble high boron rich containing molecules could be of interest for boron neutron capture therapy (BNCT) as well as for drug delivery. The reinforced electrostatic noncovalent interactions between anionic polyethylene glycol cobaltabisdicarbollide (PEG‐COSAN) branches and the ammonium cation have been shown using ESI‐MS.
