Lipophilic substituted zinc(II) phthalocyanines: 2,3,9,10,16,17,23,24-octakis[(N,N-dimethylaminoethylsulfanyl)]phthalocyaninatozinc(II) (S1) and tetrakis(N,N-dibutylaminoethoxy)phthalocyaninatozinc(II) (3) were incorporated into soybean L-α-phosphatidylcholine (SPC) liposomes of 100 nm diameter. Liposomes were characterized by static light scattering (SLS), transmission electronic microscopy (TEM), and differential scanning calorimetry. The fluorescence quantum yield and singlet molecular oxygen production of 3 are ΦF = 0.15 and ΦΔ = 0.24, respectively, whereas the same photophysical parameters for S1 are ΦF = 0.13 and ΦΔ = 0.51. Higher values of ΦF and ΦΔ are obtained in organic solvent for both dyes. Synthesis of compound 3 has also been reported.
