Photophysical properties of microencapsulated phthalocyanines

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.
