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.

Review Description
A simple and efficient 1,8-naphthalimide-based fluorescent probe ( EHN ) was designed and synthesized, in which 1,8-naphthalimide was employed as a fluorophore and the nucleophilic addition site Se-N bond of ebselen as the recognition site of H 2 S. The results of the fluorescence recognition for hydrogen sulfide (H 2 S) show that the Se-N bond of ebselen can respond to H 2 S selectively based on intramolecular charge transfer (ICT) mechanism. EHN has good fluorescence properties: large Stokes shift (106 nm) and remarkable stability at wide pH range (4 ∼ 10). EHN exhibits low LOD (0.135 μM) and fast response (within 100 s). Particularly, it has low cytotoxicity, good biocompatibility and behaves a “turn-on” effect on H 2 S. Furthermore, EHN can be used to image exogenous H 2 S in living cells and detect H 2 S in real water samples, suggesting its potential application in liveness detection and environmental protection.
