摘要
<正>An asymmetric diketopyrrolopyrrole derivative for metal ion and proton sensing Wang Liyuan, Dong Lichun, Zhou Cailong, Li Shayu, Tan Luxi Chemistry (Huaxue Tongbao), 2022, 85(11):1352～1356An asymmetric diketopyrrolopyrrole derivative TDB containing vinyl bridge, which shows deep red to near-infrared(NIR) fluorescence at 665 nm, has been synthesized. Further research shows that it has good selectivity to Ni2+and high sensitivity towards H+.
