Abstract

The quaternary ammonium complex of (2‐(methylthio)indeno[1,2,3‐gh]phenanthridin‐1‐yl)(phenyl)methanone (QAC) has been employed as a new and simple fluorescence sensor for detection of the anionic surfactant; sodium dodecyl sulphate (SDS), through fluorescence light‐up. The generation of electrostatic interaction and associated intermolecular arrangement between the probe and anionic surfactant is responsible for the fluorescence enhancement and subsequent selectivity towards the anionic surfactant. Concurrently, the probe was unaltered by the presence of cationic and non‐ionic systems. Utilizing this property, we were able to construct a facile and efficient method for the detection of anionic surfactants, featuring LOD values up to 1.1 μM concentrations in dimethylsulfoxide solvent. The light‐up detection was also confirmed via lifetime studies, with superior increments in average lifetime decay values (0.33–2.7 ns). The practical/real‐time applications of probe QAC as a sensor have also been investigated and successfully demonstrated via its ability to detect anionic surfactants from commercially available home usage products.

用于选择性检测阴离子表面活性剂的吩啶基共轭探针

(2-(甲硫基)茚并[1,2,3-gh]菲啶-1-基)(苯基)甲酮的季铵盐复合物（QAC）已被用作一种新型、简单的荧光传感器，通过荧光增亮来检测阴离子表面活性剂十二烷基硫酸钠（SDS）。探针和阴离子表面活性剂之间产生的静电作用和相关的分子间排列是荧光增强和随后对阴离子表面活性剂的选择性的原因。同时，探针在阳离子和非离子体系存在时也不会发生变化。利用这一特性，我们构建了一种简便、高效的阴离子表面活性剂检测方法，在二甲基亚砜溶剂中的 LOD 值高达 1.1 μM。发光检测还通过寿命研究得到了证实，平均寿命衰减值（0.33-2.7 毫微秒）有明显的增加。此外，还对探针 QAC 作为传感器的实际/实时应用进行了研究，并通过其检测市售家用产品中阴离子表面活性剂的能力成功地进行了演示。
