摘要：Regulating the luminescence color of single fluorescent component via non-covalent interactions has attracted considerable attentions in recent years, as its dynamic and controllable nature is favorable to develop smart luminescent materials. Herein, a supramolecular photoluminescence system with tunable fluorescence emissions ranging from yellow to green was successfully fabricated by assembling a simple fluorescent molecule, 4-(pyren-1-yl)-1-(4-vinylbenzyl)pyridin-1-ium chloride (PPD), and cucurbit[n]uril (CB[n], n = 7, 8) via host-guest interactions. Upon this assembly, PPD possessed a dramatically enhanced emission efficiency as well as a longer fluorescence lifetime. Such dynamically controllable properties with tunable fluorescence emissions enabled PPD-based assembly to be applied as fluorescent ink and have a potential in information encryption material.
