Near infrared-absorbing self-encapsulated phthalocyanine-cored polycaprolactone star polymeric nanoparticles
An octahydroxylated photosensitizing Zn phthalocyanine has been used as an initiator in ring-opening polymerization of -caprolactone. Three different phthalocyanine-core star polymers have been obtained, with each arm functionalized with either 20, 30, or 40 units. To benefit from the absorption of these polymers in the first near-infrared (NIR) phototherapeutic window, the phthalocyanine cores have been self-encapsulated into their polycaprolactone arms to yield biocompatible star polymeric nanoparticles exhibiting a remarkable absorption centered at 782 nm and an excellent logarithmic extinction coefficient value in water.
期刊介绍：
The Journal of Porphyrins and Phthalocyanines (JPP) covers research in the chemistry, physics, biology and technology of porphyrins, phthalocyanines and related macrocycles. Research papers, review articles and short communications deal with the synthesis, spectroscopy, processing and applications of these compounds.
