Fluorescence studies were run on three polyamine fluoroionophores, BD4, PeD4, and HD4 in order to determine the effectiveness of these compounds for use in trace metal detection. It was determined that the distal amine group for the 5 and 6-carbon chain compounds was too far away for there to be an electron transfer therefore making metal detection impossible by metal ion coordination fluorescence enhancement. BD4 was determined to be effective in detecting trace amounts of metals, as it caused fluorescence enhancement for the majority of metal ions tested, excluding Mercury (II) and Manganese (II). Unlike the compounds tested before, larger metals such as Cobalt (II) were more favorably coordinated than smaller metals such as Copper (II).
