【 摘 要 】
Phenanthrenequinone and terephthalaldehyde work as raw materials to fabricate TM1 in which phenanthroimidazole works as matrix. Aldehyde group react with hydrosulphite (HSO3 -) to produce addition product, in which electron gain or loss varies and intramolecular charge transfer (ICT) happens, leading to changes of absorption spectrum. According to this mechanism, HSO3 - could be detected. Convenience, fast response time and long lifespan are advantages of the novel fluorescent probe.
