dc.description.abstractAn amphiphilic block copolymer of polyphosphinoborane has been prepared by a mechanism-led strategy of the sequential catalytic dehydropolymerization of precursor monomers, H₃B ⋅ PRH₂ (R=Ph, n-hexyl), using the simple pre-catalyst [Rh(Ph₂PCH₂CH₂PPh₂)₂]Cl. Speciation, mechanism and polymer chain growth studies support a step-growth process where reversible chain transfer occurs, i.e. H₃B ⋅ PRH₂/oligomer/polymer can all coordinate with, and be activated by, the catalyst. Block copolymer [H₂BPPhH]₁₁₀-𝑏-[H₂BP(n-hexyl)H]₁₁ can be synthesized and self-assembles in solution to form either rod-like micelles or vesicles depending on solvent polarity.
