Luminescent sensors based on composites comprising transition metal complexes immobilized in polymer matrices have attracted attention as oxygen sensors for both biomedical and barometric applications. Typically, phosphorescent dyes are dispersed in a polymer matrix of high gas permeability are used. Here, S–N–P polymers are used as a novel matrix material allowing the sensitivity of the sensors to be controlled over a wide range.
