I   The hydrophilic inorganic Mo₁₅₄ macro-ions¹ (cover picture top left) show in solution an unprecedented self-assembly to giant vesicles.^2-4 For an explanation see ref. 5.

II   Each ring Mo₁₅₄ species contains 14 (7 in front, 7 at the back) well-separated compartments¹ (see also STM figure bottom right); each of these contains two delocalized electrons causing the blue colour (see III).

III   The electronic structure based on an STM study is described in ref. 6 (VIP paper, cover picture top middle).

IV   The Mo₁₅₄ and Mo₁₇₆ show unique Chemical Adaptability; see ref. 7 (VIP paper, cover picture top right).

V   Regarding a possible mechanism of formation of Mo₁₅₄ see ref. 8 (cover picture bottom left).

VI   Regarding properties related to several materials science aspects see Consequences/Applications and ref. 9.
