Temperature-driven fluorescent NOT logic is demonstrated by exploiting predissociation in a 1,3,5-trisubstituted Δ2-pyrazoline on its own and when grafted onto silica microparticles. Related Δ2-pyrazolines become proton-driven YES and NOT logic gates on the basis of fluorescent photoinduced electron transfer (PET) switches. Additional PASS 1 and YES+PASS 1 logic gates on silica are also demonstrated
通过利用 1,3,5-三取代 Δ 2 -吡唑啉本身和接枝到二氧化硅微粒上的预解离,证明了温度驱动的荧光 NOT 逻辑。基于荧光光致电子转移 (PET) 开关,相关的 Δ 2 -吡唑啉变成质子驱动的“是”和“非”逻辑门。在同一系列中还演示了二氧化硅上的其他 PASS 1 和 YES+PASS 1 逻辑门。除了这些小分子系统,基于苯并呋喃衍生的N-异丙基丙烯酰胺共聚物的聚合物分子温度计连接到二氧化硅上,以产生温度驱动的荧光 YES 逻辑。
