Application

The unique fluorescence properties of a coumarin analog, 8-methoxy-4-methylbenzo[g]coumarin (MMBC). MMBC is almost nonfluorescent in aprotic solvents, whereas it strongly fluoresces at long wavelengths in protic solvents. In the protic solvents, MMBC has a large Stokes shift. These unique features are convenient for developments of new fluorogenic sensors and devices.

Storage

-20 °C in the dark

Features And Benefits

Coumarins are aromatic lactone compounds, many of which are found in natural plants. Coumarin compounds having an electron donating group at the 7-position show strong light absorption and emission, whereas unsubstituted coumarin compounds hardly emit light. This is because intramolecular charge transfer occurs when both electron-donating and electron-withdrawing groups are present in the coumarin molecule. The introduction of groups at the 3- or 4-position largely controls the wavelength of light absorption and emission. Furthermore, the introduction of electron-withdrawing groups at these positions can enhance the luminescence intensity.
