Zhang, Junji published the artcileSoft mimic gear-shift with a multi-stimulus modified diarylethene, Formula: C15H14Cl2S2, the publication is Journal of Materials Chemistry (2009), 19(32), 5726-5729, database is CAplus.
A novel gated photochromic compound 1,8-naphthalimidepiperazine-tethered dithienylethene (Nap-Pip-DTE) was prepared to mimic a soft gear-shift based on alternative UV/Vis irradiation, protonation/deprotonation and copper(II) ion complexation/dissociation The fluorescence and absorption spectra were used as output signals. Copper(II) ion was introduced to mimic the parking (P) state by complexation with two intramol. piperazine moieties of Nap-Pip-DTE, transforming diarylethene moieties into the photoinactive parallel form.
