A naphthalocyanine dendrimer (DNPcZn) was synthesized as a potential candidate of photosensitizer for photodynamic therapy. DNPcZn exhibited strong Q band absorption around 780 nm, a useful wavelength for high tissue penetration. A polyion complex (PIC) micelle (DNPcZn/m) system was formed via an electrostatic interaction of anionic DNPcZn and poly(ethylene glycol)-poly(L-lysine) block copolymers (PEG-b-PLL).
