Abstract

Abstract: A new dyad composed of a naphthalimide unit and a spiropyran unit with a piperazine unit as the bridge has been synthesized to mimick the Three State Logic (TSL) gate and the luminescence was recorded as the output. Inputs including Protonation, deprotonation, UV irradiation and Fe 3+ coordination were employed to modulate the emission because of their distinctive outputs. Transient fluorescence and theoretical calculation were performed to further investigate the PET and FRET processes. Graphical abstract: An optimized dyad composed of spiropyran and naphthalimide bridging with piperazine was synthesized and tested for molecular logic gate mimicking Three State Logic (TSL) gate. Because its distinctive responses to UV irradiation, trifluoroacetic acid (TFA) and trimethylamine (TEA) titration and Fe 3+ coordination. Highlights: A dyad composed of a spiropyran unit and a naphthalimide unit was synthesized. The FRET effect and inhibition of PET effect were achieved as expected. The dyad was applied to mimick the Three State Logic (TSL) circuit successfully.
