DMePT-TXO2 in solution and in solid state shows dual charge-transfer (CT) emission. The CT states come from two distinctive conformations between the D and A units. Experiments show that the emission contribution of each state can be controlled by the polarity of the environment and by the excitation energy. Also, how the different conformers can be used to control the TADF mechanism is analyzed in detail. These results are important as they give a more in-depth understanding about the relation between molecular conformation and the TADF mechanism, thereby facilitating the design of new TADF molecules.",
