Abstract
Polyurethane nanocomposites with high content of red NIR luminescent transition metal clusters are presented. The gas permeability of the hybrid material is controlled by adjusting the hard/soft segment ratio of the organic matrix structure leading to a drastic and reversible enhancement of cluster luminescence depending on the molecular oxygen concentration in its surrounding atmosphere.
