New complexes (Bu₄N)₂[Mo₆X₈(n-C₃F₇COO)₆] (X = Br, I) display extraordinarily bright long-lived red phosphorescence both in solution and solid phases, with the highest emission quantum yields and the longest emission lifetimes among hexanuclear metal cluster complexes of Mo, W and Re, hitherto reported.

The interest in functional supramolecular systems for the design of innovative materials and technologies, able to fundamentally change the world, is growing at a high pace. The huge array of publications that appeared in recent years in the global literature calls for systematization of the structural trends inherent in the formation of these systems revealed at different molecular platforms and practically useful properties they exhibit. The attention is concentrated on the topics related to functional supramolecular systems that are actively explored in institutes and universities of Russia in the last 10–15 years, such as the chemistry of host–guest complexes, crystal engineering, self-assembly and self-organization in solutions and at interfaces, biomimetics and molecular machines and devices.The bibliography includes 1714 references.

Photoinactivation of Staphylococcus aureus has been achieved using a hexanuclear molybdenum cluster, [Mo ₆ I ₈ (CH ₃ COO) ₆ ] ²⁻ , supported on a polystyrene matrix.
