In recent years, organic light-emitting diodes (OLEDs) using the upconversion (UC) process mediated by triplet-triplet annihilation (TTA) have attracted increasing interest. In this study, we fabricated inverted OLEDs using soluble fullerene derivatives with different alkyl chain structures for acceptor layers and found that the alkyl chains at the interface facilitate efficient TTA-UC emission.
