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
Photoinduced generation of stable radicals is important for photochromism, photoswitching and other applications, but was limited only to a few systems. An unprecedented series of triazole-based donor-acceptor organic molecules were found to form heat/air-stable triplet diradicals in the solid state and show a clear color change through photoinduced intramolecular charge separation, which was confirmed by electron spin resonance studies, ultrafast laser flash photolysis analyses and density functional theoretical calculations. In these molecules, electron-withdrawing substituents were more beneficial to the photoinduced charge separation than electron-donating ones. Moreover, a high molecular dipole moment was more conducive to photoinduced charge separation in the presence of an electron-withdrawing substituent.
