Heterobifunctional fluorescent reagents of coumarin type are synthesized. They possess, in position 7 , a rigidized or un‐rigidized amino group and, in position 3 or 4 , a carboxylic function. The fluorescence characteristics of these compounds are described and compared with the 7‐amino‐4‐methylcoumarin. The influence of the relative freedom of rotation of the amino group or the position of the acid function on the fluorescence properties are also studied.
