Synthesis and photophysical properties of a new cationic water-soluble Zn phthalocyanine
The synthesis of tetrakis(1,1-dimethyl-2-trimethylammonium)ethylphthalocyaninato Zn(II) tetraiodide 2 - a new cationic phthalocyanine - is reported as well as its photophysical properties in water, relevant for the use of this dye as photodynamic sensitizer. The hydrophobicity of the macrocycle lead...
