Summary: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.
