Optimization of reaction temperature. (A) Effect on the fluorination yield. (B) Effect on the radioactivity recovery. (C) Effect on the fluorination efficiency. Datapoints represent average values and error bars represent standard deviations. For 100, 105, 110, 120, 130, and 140°C datapoints, the number of replicates is n = 3, 2, 3, 3, 2, 2, respectively.
