The concept of the PLATICT state is illustrated in the image. The key element is a fluorophore containing two donor (blue) and two acceptor groups (red). Absorption of UV light leads to an intramolecular charge transfer state, which is stabilized by two independent rotations. The result is the formation of the pl anarized a nd t wisted i ntramolecular c harge t ransfer (PLATICT) state. Due to the twofold rotations in the excited state, the fluorescence has a very large Stokes shift. The Cover picture was designed by Gunnar Floss (floss‐design).
