The integration of multiple chromophore units into a single molecule is expected to improve the performance of photon upconversion based on triplet−triplet annihilation(TTA-UC)that can convert low energy photons to higher energy photons at low excitation *** this study,a macrocyclic parallel dimer of 9,10-diphenylanthracene(DPA)with a precisely parallel orientation,named MPD-2,is synthesized,and its TTAUC properties are ***-2 shows a green-to-blue TTA-UC emission in the presence of a triplet sensitizer,platinum octaethylporphyrin(PtOEP).Compared to monomeric DPA,MPD-2 results in an enhancement of the spin statistical factor of TTA and a decrease in the excitation light intensity due to the intramolecular TTA *** obtained structure−property relationship provides important information for the further improvement of TTA-UC properties.
