Abstract

This work presents a coumarin-anthracene-based chemodosimeter L for the selective detection of Arginine (Arg) via hydrolysis of the imine bond of the Schiff base L. Significant changes in the emission and absorption spectra of L were observed during the detection of Arg. Chemodosimeter L displayed an impressive detection limit of 0.46 μM for Arg by the emission spectral titrations. A combination of UV-Vis, emission, and mass spectral studies, as well as excited-state lifetime measurements, and quantum yield calculations illustrated Arg-assisted dosimetry of L. The sensing of Arg by L was employed in cell imaging and for the colorimetric detection and paper test strip-based practical detection methods.

Graphical abstract

This work presents a chemodosimeter L based on a coumarin-anthracene platform for the selective detection of amino acid arginine.

用于精氨酸选择性检测的香豆素-蒽基化学剂量计

本文提出了一种基于香豆素-蒽基化学剂量计L，通过水解希夫碱L的亚胺键来选择性检测精氨酸(Arg)。在检测精氨酸时，L的发射和吸收光谱发生了显著变化。化学剂量计L对Arg的发射光谱滴定检测限为0.46 μM。结合紫外可见光谱、发射光谱和质谱研究，以及激发态寿命测量和量子产率计算，说明了精氨酸辅助剂量学对L的影响。L对精氨酸的传感用于细胞成像、比色检测和基于纸试条的实用检测方法。本文提出了一种基于香豆素-蒽平台的选择性检测氨基酸精氨酸的化学剂量计L。

期刊介绍： Journal of Chemical Sciences is a monthly journal published by the Indian Academy of Sciences. It formed part of the original Proceedings of the Indian Academy of Sciences – Part A, started by the Nobel Laureate Prof C V Raman in 1934, that was split in 1978 into three separate journals. It was renamed as Journal of Chemical Sciences in 2004. The journal publishes original research articles and rapid communications, covering all areas of chemical sciences. A significant feature of the journal is its special issues, brought out from time to time, devoted to conference symposia/proceedings in frontier areas of the subject, held not only in India but also in other countries.
