The cover picture shows that consecutive protonation of the pyridine N and imine N atoms of 4‐pyridinealdazine (PCA) in the complex [Re(4,4′‐CO 2 Me‐bpy)(CO) 3 (PCA)] + (bpy = 2,2′‐bipiridine) lead to bell‐shaped curves for both the absorbance and the emission intensity vs. pH; the latter property can be employed to devise novel luminescent pH sensors of the on‐off‐on type. Details are discussed in the article by N. E. Katz et al. on p. 5323 ff.
