Twisted intramolecular charge transfer (TICT) and twists beyond TICT: from mechanisms to rational designs of bright and sensitive fluorophores
TL;DR: The twisted intramolecular charge transfer (TICT) mechanism has guided the development of numerous bright and sensitive fluorophores as mentioned in this paper, with emphasis on understanding the structure-property relationships between the twisted geometries and how they can directly affect the fluorescence of the molecules.
