The invention relates to new macrocyclic phthalocyanine-like systems. In particular, object of the invention are new macrocyclic porphyrazine-type compounds and metal derivatives thereof, in which heterocycle rings are provided at the periphery of the inner porphyrazine fragment. A further object of the invention is a process for obtaining, as an example, tetra(thiadiazolo)porphyrazine, or tetra(selenediazolo)porphyrazine, by means of cyclotetramerization of the monomers 3,4-dicyano-1,25-thiadizole, or 3,4-dicyano-1,2,5-selenodiazole with metallorganico or inorganic salts, in organic solvents, extraction, if any, of the metal from the complexes thus formed by treatment with strong acids to obtain tetra(thiadiazolo)porphyrazine, or tetra(selenediazolo)porphyrazine, and by treatment, if any, of these compounds with a metallorganic or inorganic salt to obtain the metal derivatives thereof different from those previously extracted.
该发明涉及新的大环酞菁类系统。具体而言,该发明的对象是新的大环卟啉腙类化合物及其金属衍生物,其中在内部卟啉腙片段的周围提供了杂环环。该发明的另一个目的是通过使用有机溶剂,通过将单体3,4-二氰基-1,25-噻二唑或3,4-二氰基-1,2,5-硒二唑与金属有机或无机盐进行环四聚反应,提取如四(噻二唑)卟啉或四(硒二唑)卟啉等,通过用强酸处理从所形成的配合物中提取金属以获得四(噻二唑)卟啉或四(硒二唑)卟啉,然后通过处理这些化合物与金属有机或无机盐,以获得不同于先前提取的金属衍生物。
