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 discussed in the article by T. Torres et al. on page 2460 ff.
