- Nanoparticles can be formed via nanoprecipitation from these polymers.
- Structural and experimental parameters influence nanoparticle characteristics.

## Abstract

Double-decker (DD) lanthanide complexes of phthalocyanines
have
peculiar properties, but their structures are rarely functionalized
or incorporated into nanomaterials. This work has been conceived to
explore the feasibility of using hydroxylated DD complexes as an initiator
for Poly­(ε-caprolactone) (PCL) polymerization, with different
PCL lengths, and to investigate whether NPs suspended in water can
be obtained via the self-encapsulation of these polymers by a nanoprecipitation
process. Several structural and experimental parameters have been
tested for the nanoprecipitation process to study their potential
effects on the NP characteristics.
