fluorogenic

https://doi.org/10.1351/goldbook.FT07379
Property of a material in which fluorescence is induced or enhanced by the addition of another molecular entity.
Note:
An example is a non-fluorescent compound consisting of a pyrene connected to a maleimide group (which quenches the pyrene fluorescence). A reaction in which the maleimide moiety is converted to a succinimide derivative results in the recovery of the pyrene fluorescence.
