摘要

Fluorescence-based photoinduced electron transfer (PET) has garnered significant attention in the molecular recognition field in recent years because of its unique and desirable photophysical properties. Recent advancements in PET-based chemosensors have demonstrated their potential for real-time monitoring of pollutants such as heavy metals, pesticides, and organic contaminants in various environmental matrices. This review emphasizes the recent advancements in fluorogenic and chromogenic PET-based chemosensors based on Anthracene, Imidazole, Indole, Pyrrole, Thiazole, Naphthalene, Quinoline, Calix[4]arene, Fluorescein, Quantum Dots, Schiff base compounds and also focusing on their molecular design, sensing mechanisms, and photophysical properties reported from the year 2011 to 2024.
