Phthalocyanine. Phthalocyanine is an intensely bluegreencolored aromatic macrocyclic compound that is widely used in dyeing and the first phthalocyanine (Pc) was synthesized accidentally in 1907 as an unidentified blue compound when ocyanobenzamide was heated at high temperature and that substance is currently known to be the metalfree phthalocyanine .
Phthalocyanine Blue BN, also called by many names (EINECS 2056851), is a bright, crystalline, synthetic blue pigment from the group of phthalocyanine dyes s brilliant blue is frequently used in paints and dyes is highly valued for its superior properties such as light fastness, tinting strength, covering power and resistance to the effects of alkalis and acids.

The syntheses of new phthalocyanines (2, 3, 4, and 5) are shown in Scheme. 4Phenylethoxyphthalonitrile (1) was synthesized by the literature procedure.11 Metalfree phthalocyanine compound (2) was synthesized from the corresponding phthalonitrile compound 1 under nitrogen atmosphere in the presence of DBU in dry npentanol. The IR spectrum of
The potential use of unsubstituted aluminium phthalocyanine (AlClPc) as a sensitizer for photodynamic therapy (PDT) of cancer has not been fully exploited in spite of its higher efficiency as compared to the sulphonated derivatives. This is largely due to the strong hydrophobic character of AlClPc which renders the material difficult to
