Although a vital parameter in many colloidal nanomaterial syntheses, precursor mixing rates are typically inconsistent in batch processes and difficult to separate from reaction time in continuous flow systems. Here, we present a flow chemistry platform that decouples early-stage precursor mixing rates from reaction time (residence time) using solely off-the-shelf, commercially available, and standard dimension components. We then utilize the developed flow chemistry platform towards time- and material-efficient studies of the mass transfer-controlled synthesis of cesium lead bromide perovskite quantum dots.

自动化的流化学平台使混合和反应时间脱钩

尽管在许多胶体纳米材料合成中至关重要的参数，但前体的混合速率在批处理过程中通常不一致，并且在连续流系统中难以与反应时间分开。在这里，我们提供了一种流动化学平台，该平台仅使用现成的，市售的和标准尺寸的组件即可将早期前体混合速率与反应时间（停留时间）分离。然后，我们将利用已开发的流动化学平台，以时间和材料效率的方式研究传质受控的溴化铯铅钙钛矿量子点的传质控制。
