应用
- Electrode Based on the MWCNTs and Electropolymerized Thymolphthalein for the Voltammetric Determination of Total Isopropylmethylphenols in Spices: This study developed a sensitive electrochemical sensor for quantifying thymol and carvacrol in spices using an electrode modified with multi-walled carbon nanotubes and electropolymerized thymolphthalein (Chernousova et al., 2023).
- Fluorescence Enhancement Mechanism of Thymolphthalein-Based Probe by Coordination Interaction with Zinc Ion: This research explored the fluorescence enhancement of a thymolphthalein-based probe through coordination with zinc ions, highlighting its potential in analytical applications (Huang et al., 2021).
- pH-Triggered Visual Detection of Escherichia coli Based on the Co-Assembly of Bacitracin and Thymolphthalein: This article presents a novel method for detecting E. coli through pH-triggered visual changes using a thymolphthalein and bacitracin-based probe (Lin et al., 2023).
- Bio-Thymol Containing New High-Performance Thymolphthalein-Based Polybenzoxazine: Thermal, Superhydrophobic and Dielectric Properties: The study reports on a new polybenzoxazine material incorporating thymolphthalein, showcasing enhanced thermal, hydrophobic, and dielectric properties (Srinivasan et al., 2023).
