Metric Options: Counts1 Year3 YearSelecting 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 simple and easily synthesized colorimetric and fluorescent chemosensor 1, based on naphthol moieties as a binding and signaling unit, has been synthesized in a one step procedure. Chemosensor 1 exhibited a color change from yellow to orange and fluorescence enhancement with a red shift upon binding to Al 3+ in acetonitrile. Moreover, it can selectively detect Cu 2+ ions via an ion-promoted oxidation reaction in acetonitrile, resulting in a selective color change from yellow to dark blue and a fluorescence quenching effect. Furthermore, chemosensor 1 showed colorimetric and fluorescence selectivity for Cu 2+ in aqueous acetonitrile solution.
