To date, there are very few SF materials with high efficiencies, high stability and relatively high triplet state energy simultaneously. Diketopyrrolopyrroles (DPPs) have been found to achieve highly efficient intermolecular SF; however, they have not yet achieved efficient intramolecular SF (iSF). Herein, a series of covalently linked DPP oligomers (<em>E</em>(T<small><sub>1</sub></small>) = ∼1.1 eV) were synthesized, and their iSF properties were investigated <em>via</em> time-resolved ultrafast fluorescence/absorption spectroscopy. The absorption spectra of oligomers changed significantly compared to their corresponding monomers, suggesting the presence of strong inter-chromophore electronic coupling in these oligomers. Meanwhile, the fluorescence quantum yield of these oligomers also dropped a lot, especially in polar solvents. Transient absorption spectra revealed that these oligomers could conduct iSF in polar solvents, but not in non-polar solvents. This, together with the large dropped fluorescence quantum yield in polar solvents, suggests that iSF in these oligomers was mediated by the charge-transfer state. More importantly, the SF rate and efficiency increase gradually from dimer (∼3.71 ns and ∼45.3%) to trimer (∼1.62 ns and ∼66.8%) and then to tetramer (∼1.08 ns and ∼85.3%). This may be caused by the larger diffusion space for the separation of the triplet state provided by the increasing number of DPP units in trimers and tetramers. The 85% iSF yield of tetramers is the highest recorded for DPP derivatives in solution.
