Sensitized upconversion is explored in three metal-organic frameworks (MOFs) constructed from the anthracene dicarboxylate (ADC) derivatives and zirconium nodes, 9,10-ADC (9,10-MOF), 2,6-ADC (2,6-MOF) and 1,4-ADC (1,4-MOF). Selective excitation of surface-bound Pd(ii) mesoporphyrin IX (PdMP) gives rise to delayed fluorescence (τ = 370 ± 30 ns) from anthracene in the 9,10-MOF. The overall upconversion efficiency of the Pd@9,10-MOF is 0.46 ± 0.05% with a threshold intensity of 104 ± 26 mW cm-2.
