A novel axially substituted silicon(Ⅳ)phthalocyanine,namely di-pyridyloxy axially substituted silicon(Ⅳ)phthalocyanine 2 was synthesized and characterized by UV/vis,IR,elemental analysis,MS as well as ~1H NMR spectroscopy.Hydrophobic 2 was encapsulated by amphiphilic triblock copolymer poly[N~ε-(benzyloxycarbonyl-lysine]-poly(ethylene glycol)-poly[N~ε-(benzyl oxycarbonyl) (PLL(Z)-b-PEG-b-PLL(Z))to form hydrophobic 2-loaded polymeric complex micelle(PIC)(2-loaded PIC).Atom force microscopy(AFM)image showed that 2-loaded PIC formed a spherical nanocarrier with approximately 35-50 nm in diameter.The fluorescence intensity and lifetime of 2-loaded PIC was significantly enhanced by the incorporation 2 into PIC nanocarrier.
A novel axially substituted silicon (Ⅳ) phthalocyanine was specifically and 1H ~ 1H NMR spectroscopy. Hydrophobic 2 was encapsulated by UV / vis, IR, elemental analysis amphiphilic triblock copolymer poly [N~ε- (benzyloxycarbonyl-lysine) -poly (ethylene glycol) -poly [benzyl- oxycarbonyl (PLL (Z) -b-PEG-b-PLL hydrophobic 2-loaded polymeric complex micelle (PIC) (2-loaded PIC). Atom force microscopy (AFM) image showed that 2 spherical nanocarrier with 35-50 nm in diameter. The fluorescence intensity and lifetime of 2 -loaded PIC was significantly enhanced by the incorporation 2 into PIC nanocarrier.
