A substituted phthalocyanine in which at least one of the peripheral carbon atoms in the 1-16 positions of the phthalocyanine nucleus (MnPc) as shown in Formula (1) ##STR1## is linked via an oxygen atom or a sulphur atom to an organic radical, the remaining peripheral carbon atoms being unsubstituted or substituted by any combination of atoms or groups and sulphonated derivatives thereof. Compositions comprising one or more compounds of Formula (1) and their use as cleaning materials are also disclosed along with a process for removing stains and/or grime from fabrics using these compositions.
The use of substituted phthalocyanines for the generation of singlet oxygen in which at least one of the peripheral carbon atoms in the 1-16 positions of the phthalocyanine nucleus (MkPc) of Formula (1):
wherein:
M is selected from H, metal, halometal, oxymetal and hydroxymetal; and
k is the inverse of ½ of the valency of M;
is linked via an oxygen atom to an aromatic radical and the remaining peripheral carbon atoms are unsubstituted or substituted by any combination of atoms or groups and sulphonated derivatives thereof provided that the phthalocyanine absorbs electromagnetic radiation at a wavelength from 650 nm to 800 nm.
使用取代的酞菁生成单线态氧,其中至少一个外围碳原子位于式(1)的酞菁核(MkPc)的 1-16 位:
其中
M 选自 H、金属、卤金属、氧金属和羟金属;以及
k 是 M 的化合价 ½ 的倒数;
通过一个氧原子与一个芳香基相连,其余的外围碳原子未被取代或被任何原子或基团的组合取代,以及其磺化衍生物,条件是酞菁能吸收波长为 650 纳米至 800 纳米的电磁辐射。
