Here, a novel multi-stimuli-responsive fluorescence probe is developed by incorporating spiropyran group into the coumarin-substituted polydiacetylene (PDA) vesicles. The fluorescence of PDA can be turned on upon heating, and can be quenched upon exposure to UV light irradiation or pH stimuli owing to the fluorescene resonance energy transfer (FRET) between the red-phase PDA and the open merocyanine (MC) form of spiropyran. Moreover, we have designed and experimentally realized a set of logic gate operations for the first time based on the fluorescence modulation of the designed system upon thermal, photo, and pH stimuli. This novel type of resettable logic gates augur well for practical applications in information storage, optical recording, and sensing in complicated microenvironments.
在此,通过将螺吡喃基团引入香豆素取代的聚二乙炔(PDA)囊泡中,开发了一种新型的多刺激响应荧光探针。加热时,PDA的荧光可被开启,而由于红相PDA与螺吡喃的开环部花青(MC)形式之间的荧光共振能量转移(FRET),在紫外光照射或pH刺激下,其荧光会被淬灭。此外,我们首次基于所设计系统在热、光和pH刺激下的荧光调制,设计并通过实验实现了一组逻辑门操作。这种新型的可重置逻辑门在复杂微环境中的信息存储、光学记录和传感等实际应用中前景广阔。
