Demonstration of the fluorescence properties of 1,5-diaminoanthracene (DAA), 1-amino-5-isocyanoanthracene (ICAA), 1-N-methylamino-5-isocyanoanthracene (MICAA) and 1-N,N-dimethylamino-5-isocyanoanthracene (DIMICAA) (from top to bottom) in different solvents illuminated by light of λ = 365 nm. Solvents from left to the right are hexane, toluene, 1,4-dioxane, dichloromethane, chloroform, tetrahydrofuran (THF), acetonitrile, acetone, pyridine, methanol, dimethylformamide (DMF), dimethyl sulfoxide (DMSO), water.
