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 Fe3+ coordination were employed to modulate the emission because of their distinctive outputs. Transient fluorescence and...
Two novel pyrene derivatives 1,6-bis(3,5-diphenylphenyl)pyrene (BDPP) and 1,6-bis(2-naphthyl)pyrene (BNP) were synthesized and characterized by 1 H NMR, 13 C NMR, mass spectrum and elemental analysis. The compounds BDPP and BNP exhibit bright blue emission with high fluorescence quantum yields. The quantum chemical calculations show that BDPP has a higher non-coplanar structure compared...
