General description

7-Diethylamino-4-methylcoumarin (C1) is a bichromophoric fluorescent laser dye, which has a laser action at 460 nm.

Application

Terbium based metal organic framework may be doped with C1 for potential use in ratiometric temperature sensing. C1 may also be used as a fluorescent photo-initiator that can act as an optical brightener for use in the synthesis of the light emitting diode (LED) based hydrogel.
