Development of benzothiazole-derived rhodamine fluorescent probes for sensitive, rapid, and reversible detection and imaging of salicylic acid in food samples and plants

Rhodamine-based fluorescent sensors for the rapid and selective off–on detection of salicylic acid and their use in plant cell imaging

“…The R2 HOMO–LUMO energy gaps before and after the interaction are 3.50 and 2.52 eV, respectively, which indicates that the interaction between R2 and SA is energetically favorable and stabilizes the sensor system. 43–46…”

Fluorescent chemosensors facilitate the visualization of plant health and their living environment in sustainable agriculture

“…9a). 69 Another innovative design, chemosensor 23 , based on thiooxo-rhodamine B, involved sulfiding rhodamine spironolactam carbonyl groups to thiocarbonyl groups (Fig. 9b).…”
