Twisted intramolecular charge transfer (TICT) is an electron transfer process that occurs upon photoexcitation in molecules that usually consist of a donor and acceptor part linked by a single bond.

Donor And Acceptor

Intramolecular charge transfer results in a partial charge transfer species (Dδ+–π–Aδ−). The disconnection of π-conjugation between the donor and acceptor causes a unit-electron transfer to form D˙+–π–Si–π–A˙− species.

Chemical Inputs

We report a unimolecular system as a combinatorial logic half-subtractor based on a naphthalimide derivative. Chemical inputs (OH– and H+) can significantly change the absorption and fluorescence characteristics through modulating intramolecular charge transfer and photoinduced electron transfer process upon protonation or deprotonation of the molecule. An XOR gate is obtained following the absorbance variations at 485 nm, and an INHIBIT gate is induced when the output signal is monitored at 535 nm in the fluorescence spectra. Large differences in output signals allow unequivocal assignment of logic-0 and logic-1 of both logic gates, which may function in parallel to implement the half-subtractor.
