Metric Options: CountsSelecting the 1-year or 3-year option will change the metrics count to percentiles, illustrating how an article or review compares to other articles or reviews within the selected time period in the same journal. Selecting the 1-year option compares the metrics against other articles/reviews that were also published in the same calendar year. Selecting the 3-year option compares the metrics against other articles/reviews that were also published in the same calendar year plus the two years prior.
Example: if you select the 1-year option for an article published in 2019 and a metric category shows 90%, that means that the article or review is performing better than 90% of the other articles/reviews published in that journal in 2019. If you select the 3-year option for the same article published in 2019 and the metric category shows 90%, that means that the article or review is performing better than 90% of the other articles/reviews published in that journal in 2019, 2018 and 2017.

Article Description
A novel electron-deficient heteroacene 15H-pyrazino[2:3′,4′]pyrrolo[1′,2′:1,2]imidazo[4,5-b]phenazin-15-one (1) has been successfully synthesized and characterized. Compound 1 can selectively recognize CN and F over other 10 anions including BF, PF, Cl, SO, NO, I, HPO, ClO, Ac, and Br in CHCl/DMF mixed solvents with dual responses, including absorption signals and fluorescent "turn-off" effects. CN and F can be distinguished by the completely quenched fluorescence (for CN) and partially reduced fluorescence (for F). Especially, compound 1 exhibits higher sensitivity to CN than F with the response concentration as low as 5.0 × 10 mol/L. Moreover, compound 1 shows very interesting solvatochromism effect, and the CHCl solution of compound 1 is sensitive to triethylamine, and its emission could change from green to red upon the addition of triethylamine, which is attributed to the n-π intermolecular charge-transfer interaction.
