a Mass spectrum of 4-bromoaniline-containing MeOH/H2O microdroplets using N2 as the nebulizing gas. b MS2 spectrum of the peak at m/z 185.11 shown in (a). c Mass spectrum of 4-iodoaniline-containing MeOH/H2O microdroplets using N2 as the nebulizing gas. d Influence of the reaction time on the intensity ratio of C12H13N2+/C6H7NBr+. Heatmap of signal intensity of C12H13N2+ generated with (e) varied reaction time and nebulizing gas pressure, and f varied reaction time and solution concentration. Each error bar represents the standard deviation of three experiments.
