Verfahren zur Durchführung einer Reaktion mit Singlett-Sauerstoff unter Einsatz von wasserlöslichen Azaphthalocyaninen und diese enthaltende Mittel

摘要

Novel azaphthalocyanines are described which are of the formula in which Me is Al(III), Zn(II), Ge(IV) or Sn(IV), E is an anionic group, Z is a cation, Y is a halogen, n is any desired number from 1 to 3 and p is any desired number from 0 to 2, the sum n+p being at most 8 and A, B, C and D independently of one another completing a benzene ring or a ring of the formula +TR at least one of the rings completed by A, B, C or D being one of the said heterocyclic rings. The novel compounds can be used as photoactivators, in particular for bleaching textiles and for controlling microorganisms in or on organic or inorganic substrates. Bleaching, washing and steeping agents and antimicrobially active agents are also described which contain the novel azaphthalocyanine compounds. The azaphthalocyanine pigments which arise as intermediates and which do not carry groups EZ imparting solubility in water, their preparation and their use as photosensitizers in non-aqueous or heterogeneous systems are likewise described.
