Abstract

This paper describes a simple platform that employs coumarin dye-encapsulated semiconducting polymer dots as a fluorescent probe for ratiometric and sensitive fluoride anion detection, in which the sensing mechanism is based on the deprotection of the tert-butyldimethylsilyl group on coumarin to induce Förster resonance energy transfer.

摘要

本文描述了一个简单的平台，该平台采用包裹香豆素染料的半导体聚合物点作为用于比率式和灵敏氟离子检测的荧光探针，其中传感机制基于香豆素上叔丁基二甲基硅烷基的脱保护以诱导福斯特共振能量转移。
