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