WebDec 1, 2024 · M2 state possesses the largest potential energy and shows the same structure as Lb-S 1, which is a dark state with the oscillator strength 0.0017. A very large barrier is observed between M1 and M2, indicating the Lb-S 1 TICT state is not attainable. Thus, this TICT state is not likely to exist. WebSep 1, 2024 · And the dark TICT state is susceptible to environmental polar solvents. However, PTAs based on fluorophores with intramolecular motion could finely tune energy dissipation between radiative and non-radiative decay through molecular engineering with sufficient molecular motors. In this section, we would discuss how to regulate excited …
