摘　　要：荧光防伪技术是指将特殊的荧光材料制备成防伪标识,借助辅助的激发光显示加密信息的防伪技术。荧光防伪材料需要在多种状态下使用,因此要求荧光材料在不同状态下都能够高效的发光。双态发光(dual-state emission,DSE)分子是一类在单分子状态下和聚集状态下都具有强烈发光性能的分子。4-(二苯氨基)(苯基)乙酮(Acetyl-TPA)分子是一类典型DSE分子,其合成方法简单、荧光强度高,在不同极性溶剂中表现出不同颜色的荧光特性使得这一类分子成为防伪印刷领域的一种极佳选择。本实验通过傅克酰基化亲电取代反应一步制备Acetyl-TPA分子,并进一步探索了其在防伪印刷中的应用;本实验原料低廉易得、安全性高,通过本实验训练,学生不仅掌握了芳香酮类化合物的制备方法,同时也了解了DSE分子的发光特性及其在防伪领域中的应用。具有一定的科学启发性。Fluorescent anti-counterfeiting technology refers to the anti-counterfeiting technology that prepares special fluorescent materials into anti-counterfeiting labels and displays encrypted information with the help of auxiliary excitation light.Fluorescent security materials need to be used in a variety of states,so fluorescent materials are required to be able to emit light efficiently in different states.Dual-state emission(DSE)molecules are a class of molecules with strong luminescence properties in both single-molecule and aggregate states.1-(4-(diphenylamino)phenyl)ethan-1-one(Acetyl-TPA)molecule is a typical class of DSE molecules,which has a simple synthesis method,high fluorescence intensity,and different color fluorescence characteristics in different polar solvents,making this type of molecule an excellent choice in the field of anti-counterfeiting printing.In this experiment,Acetyl-TPA molecules were prepared by Friedel-Craftyl electrophilic substitution reaction in one step,and its application in anti-counterfeiting printing was further explored.It has a certain scientific enlightenment.
