OPTICAL RECORDING MEDIUM AND NOVEL AZAPORPHYRIN COMPOUNDS

摘要

An optical recording medium comprises a recording layer containing a metal complex of mono-, di- or triazaporphyrin. Independent claims are also included for: (i) a compound of formula (1); and (ii) preparation of (1) by reacting (9) and (10) with halogenated metal and metal derivatives. [Image] R81> and R82> can form an optionally substituted alicyclic ring via a connecting group. A, B, C, D : optionally substituted pyrole ring skeletons; X, Y, Z : methylene having a substituent(s), at least one of the substituents is methine; M : 2 - 4 valent metal atom or half metal atom having 2H, substituents or ligands or oxy metal atom; R81> - R86>H, halogen, hydroxyl, optionally substituted alkyl, aryl, alkoxy, aralkyloxy, aryloxy, alkenyloxy, alkylthio, arylthio or heteroaryl, Q : halogen, cyano.
