title: Azaphthalocyanines with fused triazolo rings: formation of sterically stressed constitutional isomers.
abstract: The presented work deals with synthesis and isolation of constitutional isomers of triazolo-fused azaphthalocyanines. Distribution of the isomers did not follow the statistical calculations due to steric effects of the substituents preferring the least sterically stressed C(4h) isomer.
