In the modern day, chemistry governs the very essence of life on a sub-atomic level from simple toothpaste to life-saving drugs, we depend on the chemicals that constitute the very essence of existence itself. Therefore, the detection and study of these chemicals recognized as an absolute necessity because along with pros comes the cons, i.e., the toxicity & the notorious side effects of the very same chemicals. Thus, certain compounds called ‘Chemo-sensors’ specialise in trapping target chemical entities which could be separated later or create specific fluorescent lights, making them visible to the naked eye. One such type of ‘fluorescent chemo-sensor is the family of chemicals called Coumarins. From the topic, we come across the family of Coumarins that can help detect the Cyanide ions (CN–) following the mechanism involving nucleophilic addition and intermolecular charge transfer (ICT), resulting in high fluorescence.
