Twisted intramolecular charge shuttle (TICS): In TICS systems, the donor and acceptor moieties dynamically switch roles in the excited state due to an approximately 90° intramolecular rotation that is induced upon photoexcitation. This results in charge shuttling. TICSs exist in several families of fluorophores and could be utilized in the construction of fluorescent probes.
