Abstract
The present work describes development of a simple and cost-effective fluorescence sensor for determination of quinone specially 1,8-dihydroxyanthraquinone (danthron). A 2D-metal-organic framework (TMU-54) containing the azobenzene group has been synthesized and applied as an efficient fluorescent sensor for danthron detection. The key feature that has a great impact on the properties of the material is the presence and distribution of functional groups within the structure. We discuss the relationship between the nature and structure of the specifically designed organic linker as well as the properties of this framework in fluorescence recognition of quinones. TMU-54 ([Cd3(adc)6(DMF)2]) is capable of distinguishing complementary and mismatched target sequences with high sensitivity and a significant Ksv (1049) value.
