Procedure for the preparation ofnsubphthalocyanines with high solubility and high optical stability withnapplications such as materials for optical storage ofndata.n n n Procedure for the preparation ofnsubphthalocyanines with high solubility and high optical stability withnapplications such as materials for optical data storage ofnCD and DVD discs, where R 1, R 2, R 3,nR 4, R 5, R 6, R 7 and R 8 representnindistinct a hydrogen atom, or a functional groupnelectron attractor, such as a halogen atom, a groupnnitro, sulfoxide or sulfone or an electron donor group suchnas an alkoxide or thioether group, where R 9 represents an atomnof halogen, an aryloxy or arylthio group. |
