Lewis acid-base adducts resulting from instantaneous interactions provide a cost-effective strategy for color tuning and anticounterfeiting information. Herein, we report the construction of luminescent Lewis acid-base adducts via inkjet printing. Due to the unique weak coordination bond of B→N, it is feasible to construct anticounterfeiting information that is easy to erase. The in situ postsynthesis of the luminescent quick response codes via inkjet printing facilitates precision chemistry control to change the emission ranging from deep-blue (peaking at 407 nm) to orange-red (peaking at 597 nm). The encrypted information can be quickly erased either by modulating the temperature to dissociate the weak coordination or strong Lewis base to promote a neutralization reaction.
由瞬间相互作用产生的路易斯酸碱加合物为颜色调节和防伪信息提供了一种经济高效的策略。在此，我们报告了通过喷墨打印构建发光路易斯酸碱加合物的方法。由于独特的B→N弱配位键，构建易于擦除的防伪信息是可行的。通过喷墨打印原位合成发光快速响应码有助于精确控制化学过程，从而改变发射光，使其从深蓝色（峰值在407nm）到橙红色（峰值在597nm）。通过调节温度使弱配位解离或使用强路易斯碱促进中和反应，均可快速擦除加密信息。
