| Popis: | The tunable photochromic systems have received wide attention in the photoelectronic fields. Herein, we report a diarylethene derivative attached with 2-hydrazylbenzothiazole via Schiff base, which shows the typical photochromic properties upon alternating irradiation with UV and visible light. Remarkably, the varying binding mode and complex strength between the diarylethene and selective metal ions (Cu2+, Ni2+, Cr3+, Sn2+ and Al3+) enable the methanol solution of the diarylethene to exhibit stepwise photochromic reactivity by virtue of these metal ions. The photochromic reactivity of the diarylethene could be suppressed at different levels by the formation of the complex with Cu2+ and Ni2+ in a 2:1 binding mode, respectively, whereas the photochromic reactivity was enhanced to varying degrees by Cr3+, Sn2+ and Al3+ in a 1:1 binding mode. Based on these multiple stimuli responses, a logic circuit with six input signals and three output signals was constructed to perform complex logical operations at the single molecular level. |
