The core of the paper by Wei Lu, Dan Chen, Han Jiang, Liming Jiang, and Zhiquan Shen on page 590 includes two parts: the selective and sensitive recognition of fluoride through the obtained copolymer-based probe poly(MMA-co-VNT), as well as the fabrication of the molecular-scale complementary “INHIBIT/IMPLICATION” logic gates. Accordingly, the cover image designed is also composed of two parts. The first part demonstrates the selective recognition process: the colorless solution of poly(MMA-co- VNT) becomes yellow upon binding of fluoride ions. The second part describes the logic gates: the logic circuit at the bottom right of the cover image represents the function of complementary “INHIBIT/IMPLICATION” logic gates.
