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
The anionic polymerization of N-vinylcarbazole (NVC) by using optically active anionic initiators such as the lithium salts of (S)-1-(9H-fluoren-2-yl)-4-isopropyl-4,5-dihydrooxazole ((S)-1-FIDH) and (S)-2-(9H-fluoren-2-yl)-4- isopropyl-4,5-dihydrooxazole ((S)-2-FIDH) and complexes of (-)-Sparteine with n-butylithium (n-BuLi-(-)-Sp) or fluorenyl lithium (FILi-(-)-Sp) was achieved. The yield and specific rotation of poly(N-vinylcarbazole)s (poly(NVC)s) were considerably affected by the molar ratio of (S)-FIDH to NVC. The highest yield and specific rotation were obtained with Li- (S)-1-FIDH as an initiator, with a molar ratio of monomer and initiator [M]/[I] = 10/1. The effects of the chiral initiators, type of solvent and the polymerization temperature were investigated. The obtained optical activity of polymers was attributed to asymmetric induction of the chiral initiators.
