Abstract

A versatile mono-Schiff compound consisting of -aminobenzene-hydroxyjulolidine (ABJ-MS) has been easily synthesized using a one-step reaction. ABJ-MS displays four diverse fluorescence responses to the addition of Zn/Al/Fe/Ag, with the maximum fluorescence emission at 530 nm undergoing a hypsochromic shift to 502/490/440/430 nm, synchronously with the discriminating fluorescence enhancement being 10.6/22.8/2.6/7.1-fold, respectively. However, the addition of Cu into ABJ-MS leads to an opposite behavior, namely, fluorescence quenching. Meanwhile, ABJ-MS also displays distinct absorption changes after adding these five metal ions due to different binding affinities between them and ABJ-MS, which gives ABJ-MS quite a versatile detecting nature for Cu/Zn/Al/Fe/Ag. Moreover, ABJ-MS can mimic a series of versatile AND/OR/INH-consisting logic circuits on the basis of the Cu/Zn/Al/Fe/Ag-mediated diverse optical responses. These will endow the smart ABJ-MS molecule and potential applications in the multi-analysis chemosensory and molecular logic material fields.

摘要

一种由-氨基苯-羟基朱利啶（ABJ-MS）组成的多功能单席夫碱化合物已通过一步反应轻松合成。ABJ-MS对添加的锌/铝/铁/银呈现出四种不同的荧光响应，最大荧光发射波长在530nm处，发生蓝移至502/490/440/430nm，同时荧光增强倍数分别为10.6/22.8/2.6/7.1倍。然而，向ABJ-MS中加入铜会导致相反的现象，即荧光猝灭。同时，由于这五种金属离子与ABJ-MS之间的结合亲和力不同，加入这些金属离子后ABJ-MS也会呈现出明显的吸收变化，这使得ABJ-MS对铜/锌/铝/铁/银具有相当广泛的检测特性。此外，基于铜/锌/铝/铁/银介导的多种光学响应，ABJ-MS可以模拟一系列由与/或/抑制组成的多功能逻辑电路。这些将赋予智能ABJ-MS分子在多分析化学传感和分子逻辑材料领域的潜在应用。
