✦ Synopsis

The cover picture shows a space-filling representation of an intrinsically unsymmetrical porphyrazine containing a transition metal ion within its central cavity (C atoms in green, N atoms in red, metal atom in yellow and H atoms in white). The formal substitution of a pyrrole ring in a metalloporphyrazine by the 1,2,4-triazole moiety does not produce any substantial variation in the nature of the macrocycle, as it is revealed by its UV/Vis spectrum which is represented in the lower left-hand corner. The symmetry reduction of the porphyrazinic core is spectroscopically evidenced by the splitted Soret and Q-bands. Details of the synthesis and spectroscopical properties of this promising porphyrazine family is
