- Abstract:
- We demonstrate the synthesis of star-shaped
poly(2-ethyl-2-oxazoline) featuring a porphyrin core starting
from alkyne-functionalized porphyrin ([TPP-TB] 4 ) and
azide-functionalized poly(2-ethyl-2-oxazoline) (PEtOx-
N 3 ) via copper-catalyzed azide-alkyne cycloaddition
(CuAAC). The porphyrin core was further utilized for the
complexation of either copper or iron within the central
cavity. The obtained materials were investigated using a
combination of nuclear magnetic resonance spectroscopy,
fourier transform infrared spectroscopy, ultravioletvisible
spectroscopy, size-exclusion chromatography, and
matrix assisted laser desorption/ionization time-of-flight
mass spectrometry. In the case of copper, the inclusion of
the metal ion was achieved in a one-pot reaction during
the CuAAC reaction for attaching the PEtOx-N 3 arms.
