The synergetic effect on the efficiency of triplet–triplet‐annihilation‐assisted photon upconversion, as a result of a synthetic procedure for simultaneous and independent optimization of the intrinsic efficiencies of triplet–triplet transfer and triplet–triplet annihilation, is demonstrated (see picture). The new system shows high upconversion quantum yields of order of 0.11.
