Multiexciton quintet states, 5(TT), photogenerated in organic semiconductors using singlet fission (SF), consist of four quantum entangled spins, promising to enable new applications information science. However, the factors that determine spin coherence these states remain underexplored. Here, we engineer packing tetracene molecules within single crystals 5,12-bis(tricyclohexylsilylethynyl)tetracene (TCHS-tetracene) demonstrate a 5(TT) state exhibits qubit properties, including time, T2, = 3 μs at 10 K, population lifetime, Tpop, 130 5 and stability even room temperature. The single-crystal platform also enables global alignment spins and, consequently, individual addressability spin-sublevel transitions. Decoherence mechanisms, exciton diffusion, electronic dipolar coupling, nuclear hyperfine interactions, are elucidated, providing design principles for increasing T2 operational temperature 5(TT). By dynamically decoupling from surrounding bath, is achieved. These results viability harnessing initiate multiple electron well-defined next-generation molecular-based technologies.
