Abstract

The amphiphilic diblock copolymer (MEEP-Ph/MEEP) with [N = P(OCH₂CH₂OCH₂CH₂OCH₃)₂]_n (MEEP) as a hydrophilic block and [N = PPh(OCH₂CH₂OCH₂CH₂OCH₃)]_m (Ph/MEEP) as a hydrophobic block was synthesized through a controlled cationic polymerization of phosphoranimine. MEEP-Ph/MEEP self-associated to form micelles with a critical micelle concentration of 80 mg/L in an aqueous solution. The steady-state fluorescence anisotropy value of DPH in a block copolymer solution was 0.237. The analysis of the fluorescence lifetime of DPH in the MEEP-Ph/MEEP solution indicated that the micellar core region was fairly polar and consisted of two hydrophobic domains with different polarity.
