Figure 1c shows the molecular structures of the tetracene oligomers studied in this work. The details of the synthesis methods are reported elsewhere33,34. The tetracene dimer, trimer and tetramer exhibit structures with benzene-linked tetracene subunits. Their similar absorption peak positions (Fig. 1d) … See more To further confirm the role of the 1(T…T) state in the iSF processes, we probe the iSF dynamics in the oligomers under an external magnetic field. The … See more The most intriguing potential of the 1(T…T) state is its ability to dissociate into free triplets with a markedly enhanced efficiency in comparison with the 1(TT) state. … See more Next, we try to understand the generation mechanisms of the two different TT states. In general, the intermediate states of correlated triplet pairs can be … See more WebMar 30, 2024 · Triisopropylsilylethynyl-substituted acenes (TIPS-acenes) have received prominent attention in the field of singlet fission, the pentacene derivative being an exothermic singlet fission material, and the tetracene being a …
