摘　　要：本文设计合成了一种含有扭曲的三苯胺和刚性的蒽环的新型荧光传感材料AT-DPIT,并利用紫外吸收和荧光光谱对AT-DPIT的性能进行了系统的研究。由于氮原子在咪唑环上的特殊质子结合能力,ATDPIT表现出显著的酸致变色性质,随着酸的加入,化合物AT-DPIT的溶液荧光颜色从最初明亮的黄色逐渐猝灭为无色。此外,AT-DPIT的CH3CN溶液对Cu^(2+)检测表现出高选择性、高灵敏度和抗干扰性,检测限达1.62×10^(−7)mol·L^(−1)。因此,AT-DPIT可以作为应用广泛的多功能荧光传感器。This work describes the design and synthesis of AT-DPIT,a new fluorescent sensing material with stiff anthracene rings and twisted triphenylamine.The properties of AT-DPIT were systematically investigated using UV absorption and fluorescence spectroscopy.Due to the exceptional proton binding ability of the nitrogen atoms on its imidazole ring,ATDPIT exhibits notable acidochromic properties.With the addition of acid,the fluorescent color of the AT-DPIT solution gradually bursts from the initial bright yellow to colorless.Furthermore,the CH_(3)CN solutions of AT-DPIT demonstrate high selectivity,high sensitivity,and anti-interference for Cu^(2+)detection,enabling a limit of detection for Cu^(2+)at 1.62×10^(−7)mol·L^(−1).Consequently,these potential luminophores were synthesized as convenient and promising multifunctional sensors.Therefore,AT-DPIT can be used as multifunctional fluorescent sensor for a wide range of applications.
