摘要

Compared with most of the reported logic devices based on the supramolecular approach, systems based on individual molecules can avoid challenging construction requirements. Herein, a novel dioxoporphyrin DPH_(22) was synthesized and two of its tautomers were characterized by single-crystal X-ray diffraction studies. Compound DPH_(22) exhibits multichannel controllable stepwise tautomerization, protonation, and deprotonation processes through interactions with H~+ and F~- ions. By using the addition of H~+ and F~- ions as inputs and UV/Vis absorption values at λ=412, 510, 562, and 603 nm as outputs, the controlled tautomerism of DPH_(22) has been successfully used for the construction of an integrated molecular level half-subtractor and comparator. In addition, this acid/base-switched tautomerism is reversible, thus endowing the system with ease of reset and recycling; consequently, there is no need to modulate complicated intermolecular interactions and electron-/chargetransfer processes.
