Abstract

-terphenylene bridging units were quantified to be 112 ± 6%, 132 ± 2%, and 128 ± 4%, respectively, in solution. The drop of fluorescence lifetimes of the SF dimers at high concentrations of the molybdenum complex implies energy transfer from exchange-coupled triplet pairs, highlighting the importance of controlling exchange interaction and triplet pair recombination. This work represents a significant step toward developing exciton/photon amplification materials by combining SF materials with transition-metal complexes, advancing the application of SF beyond conventional limitations.
