7-Diethylamino-4-methylcoumarin

7-Diethylamino-4-methylcoumarin (also called Coumarin 1 or Coumarin 460) is a bichromophoric fluorescent laser dye. It can be used as a laser dye, a luminescent phosphor in LEDs, a luminescent probe and sensor in biological applications, and a fluorescer in rewritable optical drives. The efficient fluorescent property of this compound is utilized to sense the Pd2+ selectively and sensitively.It is also used as a fluorescent whitening agent (FWAs), which is a chemical added to fabrics and paper during manufacture to increase whiteness and brightness. Spectral data: lambdaex: 373nm (ethanol), lambdamax: 460nm, Laser range: 450-484nm. References: (1) K. Kato, IEEE J. Quantum Electron. 11, 373 (1975) , (2) S. Vajda, et al., J. Chem. Soc.
