Phthalocyanines of the formula
where
Me is twice hydrogen, twice lithium, magnesium, zinc, copper, nickel, VO, TiO, AlCl, AlOH, AlOCOCH3, AlOCOCF3, SiCl2 or Si(OH)2,
at least four of the radicals R1 to R16 are each independently of the others a five- or six-membered saturated nitrogen-containing heterocyclic radical which is bonded to the phthalocyanine structure via a ring nitrogen atom and which can additionally contain further hetero atoms, and
any remaining radicals R1 to R16 are each hydrogen, halogen, hydroxysulfonyl or C1-C4-dialkylsulfamoyl,
subject to the proviso that tetrakispiperidinylphthalocyanine shall be excluded,
and heterocyclyl-substituted phthalocyanines are useful for marking liquids, in particular mineral oils.
公式为的酞菁类化合物,其中Me表示两个氢、两个锂、镁、锌、铜、镍、VO、TiO、AlCl、AlOH、AlOCOCH3、AlOCOCF3、SiCl2或Si(OH)2,至少四个基团R1到R16各自独立地是五元或六元饱和含氮杂环基团,通过环氮原子与酞菁结构键合,且还可以包含其他杂原子,任何剩余的基团R1到R16各自是氢、卤素、羟基磺酰基或C1-C4二烷基磺酰基,但四(吡啶基)酞菁应予以排除。含杂环基团的酞菁类化合物可用于标记液体,特别是矿物油。
