Cover Feature: Triplet–Triplet Annihilation Upconversion in a MOF with Acceptor‐Filled Channels (Chem. Eur. J. 5/2020)

Abstract

Green to blue triplet–triplet annihilation upconversion was achieved in the solid state. A mesoporous metal–organic framework with palladium porphyrin walls hosts anthracene triplet acceptors in its hydrophobic channels. This stable crystalline material shows efficient triplet–triplet annihilation upconversion in the solid state. More information can be found in the Communication by U. Resch‐Genger, K. Heinze, et al. on page 1003.
