OPTICAL DATA MEMORIES COMPRISING COBALT PHTALOCYANIN WITH AN AXIAL SUBSTITUENT AND AXIAL LIGAND IN AN INFORMATION PHOTOINSCRIBTIBLE LAYER

摘要

Cobalt (III) phalocyanin of the present invention relates to a kind of light absorption chemical species containing at least one optical data media is in Information Level. The center of metal Co has an axial substituent R1 and an axial ligand R2 to be provided with coordinate bond. R1 is CN, SCN, and halogen entombs Cl, Br or F of lines, alkoxy, aryloxy group, arythio or alkylthio group, and R2 is not that amine, water, alcohol, mercaptan or isonitrile H2S is finally replaced in ligand or one.
