Solutions of fluorescent compounds are typically used as reference materials by industry and government to accurately calibrate the analytical equipment used in water and food quality analyses. But, rather than using solutions, it would be preferable to make use of robust, malleable materials, e.g., polymer films, to improve the longevity and versatility of fluorescence standards. This project will employ organic synthesis (in the McGonigal Group) and spectroscopic analysis (in the Monkman Group) to pioneer new solid-state fluorescence standards, building on our work recently published in Chem. Sci. 2020, 11, 6990-6995 . The SOFI2 student will (i) synthesise a series of fluorescent monomers, (ii) optimise conditions for their polymerisation and formulation, and (iii) measure their absorption and emission properties spectroscopically.

荧光化合物的溶液通常被工业和政府用作标准材料，以准确校准水和食品质量分析中使用的分析设备。但是，与其使用溶液，不如使用坚固的、可延展的材料，例如聚合物薄膜，以提高荧光标准的使用寿命和通用性。这个项目将采用有机合成（在McGonigal小组）和光谱分析（在Monkman小组）来开拓新的固态荧光标准，以我们最近发表在Chem上的工作为基础。科学通报，2020,11,6990-6995。SOFI2学生将(i)合成一系列荧光单体，（ii）优化其聚合和配方的条件，以及（iii）用光谱测量其吸收和发射特性。
